A Parker Asahi cutting board requires less maintenance than a wooden board, but it still needs regular care. Stains, odors, warping, and visible knife marks usually come from delayed cleaning, excessive heat, dishwasher use, or poor storage.
The good news? Synthetic rubber is simple to maintain. You don’t need mineral oil, wax, or cutting board conditioner. For daily care, wash the entire board with neutral dish soap, rinse it well, dry it fully, and store it either flat or perfectly upright.
Follow the right routine, and your Parker Asahi rubber cutting board can remain hygienic, stable, and gentle on Japanese knife edges for years.
How Should You Care for a Parker Asahi Cutting Board?
Wash a Parker Asahi cutting board by hand after every use. Use neutral dish soap with a soft sponge or kitchen brush. Clean the front, back, and all four edges, then rinse the board thoroughly and remove as much water as possible. Let it dry completely before storage.
Never place the board in a dishwasher or heated dish dryer. Keep it away from direct flames, boiling-water baths, hot cookware, and long periods of bleach soaking. Store it flat or completely vertical. Don’t leave it leaning against a wall or cabinet.
If ordinary washing no longer removes shallow knife marks or permanent stains, refresh the surface with a dedicated cutting board scraper, such as the Fuchioka MS-83, or waterproof sandpaper of around #100 grit.
Quick answer: Hand-wash the board, dry it completely, protect it from high heat, and resurface it only when normal cleaning no longer works.
Why Does a Parker Asahi Rubber Board Need Different Care from a Wooden Board?
A Parker Asahi board is made from synthetic rubber, so it doesn’t need the oiling, waxing, or seasoning used for wooden cutting boards. Its maintenance is based on regular washing, thorough drying, safe sanitation, and protection from heat.
Wood absorbs moisture. It can dry unevenly, lose its protective oils, and eventually crack. Synthetic rubber behaves differently. It resists moisture and dries fairly quickly, but excessive heat or uneven pressure can change its shape.
The material also cushions the knife edge more effectively than glass, stone, or hard plastic. This softer contact helps protect thin Japanese blades, although knife marks will still appear after long use. That’s normal. A cutting board is a working surface, after all, not a museum piece.
Parker Asahi states that its Cookin’ Cut boards combine scratch resistance with a softer cutting feel. The material also receives an antibacterial treatment. However, bacteria can still grow if food residue remains on the surface.
A rubber cutting board needs less restorative maintenance than wood, but it still needs to be washed after every use.
What Should You Do Before Using the Board?
Wet the cutting surface with clean water before preparing strongly colored, oily, or aromatic ingredients. Wipe away the excess so the board feels damp rather than wet.
A thin layer of water creates a temporary barrier between the surface and food juices. It can help reduce stains and lingering odors, especially from ingredients with strong pigments or oils.
This step is useful when preparing:
- raw fish;
- raw meat;
- turmeric;
- beetroot;
- carrots;
- tomatoes;
- garlic;
- onions;
- oily sauces;
- strongly colored spices.
Don’t leave standing water on the board. Too much water can make ingredients slide, and pooled water underneath may reduce the board’s grip on the countertop.
Before you start cutting, check that the board sits firmly in place. If it moves, place a clean damp kitchen towel or a suitable non-slip mat underneath it.
Quick answer: Dampen the cutting surface before preparing food that may stain or leave odors, but keep the underside stable and free from pooled water.
How Do You Clean a Parker Asahi Cutting Board After Daily Use?
Wash the board as soon as you finish using it. Use warm water, neutral dish soap, and a soft sponge or kitchen brush. Clean the top, bottom, and all four edges rather than washing only the visible cutting area.
A good daily cleaning routine looks like this:
- Remove food scraps. Clear away residue before it dries. Don’t scrape the surface with the sharpened edge of your knife.
- Apply neutral dish soap. Use a soft sponge or a medium-soft kitchen brush. Metal scourers are too aggressive for daily cleaning.
- Wash the cutting surface. Pay extra attention to areas used for fish, meat, garlic, onions, spices, or oily foods.
- Clean the underside and edges. Water, grease, and food residue can easily spread beneath the board while you work.
- Rinse thoroughly. Remove all soap and loosened residue with clean running water.
- Wipe away excess water. Dry both sides and every edge with a clean towel.
- Let the board air-dry. Don’t put it in a cupboard while it is still damp.
Parker Asahi recommends washing the front, back, and sides before drying the board. Grease and strong-smelling ingredients should be removed as soon as possible.
Cleaning only the top may seem enough, but it leaves half the job unfinished. Moisture and food residue often hide underneath, where they can cause odors and hygiene problems.
Quick answer: Wash every surface after each use. The underside and edges need the same attention as the cutting face.
Can You Put a Parker Asahi Cutting Board in the Dishwasher?
No. Parker Asahi rubber cutting boards should always be washed by hand. Dishwasher heat can permanently warp or deform the synthetic rubber.
A dishwasher exposes the board to several harsh conditions at once:
- sustained high temperatures;
- strong detergent;
- pressurized water;
- prolonged moisture;
- uneven support inside the rack;
- heated drying.
A board may look unchanged after one dishwasher cycle, but repeated exposure can slowly alter its shape. Even a slight curve may cause it to rock on the countertop, which makes knife work less stable and less safe.
Parker Asahi states that its household cutting boards are not dishwasher-safe. Its professional board instructions also prohibit dishwashers and heated dish dryers.
Quick answer: Heat resistance doesn’t make the board dishwasher-safe. Wash it by hand every time.
Can You Use Bleach on a Parker Asahi Rubber Cutting Board?
Yes. You can sanitize a Parker Asahi board with a properly diluted household bleach solution. However, you shouldn’t leave it soaking in bleach for a long time.
Use bleach for occasional sanitation or stubborn stains, not as your main daily cleaner. Wash the board with dish soap first. Grease and food residue can block the sanitizer from reaching the surface properly.
USDA guidance for food-contact surfaces gives a ratio of one tablespoon of unscented liquid chlorine bleach per US gallon of water. That equals about 4 ml per liter. Apply the solution to the clean surface, leave it for several minutes, then rinse the board thoroughly and dry it.
Parker Asahi warns against prolonged bleach soaking. Bleach may also cause some discoloration on light-colored boards, although this doesn’t always affect their performance.
Follow these rules when using any chemical sanitizer:
- use the concentration stated on the product label;
- never mix bleach with vinegar, ammonia, or other cleaners;
- wash the board before sanitizing it;
- treat both working surfaces;
- observe the required contact time;
- rinse the board when the instructions require it;
- dry it completely before storage.
More bleach doesn’t mean better cleaning. A strong solution or a long soak may damage the surface without improving hygiene.
Quick answer: Use diluted bleach briefly after washing. Don’t leave the board submerged in a concentrated bleach solution.
How Should You Clean the Board After Raw Meat or Fish?
Wash the board immediately after preparing raw meat, poultry, fish, or seafood. Use hot soapy water, then sanitize the surface before placing ready-to-eat food on it.
A practical food-safety routine is:
- Remove all visible food residue.
- Wash the board, knife, and nearby countertop with dish soap.
- Rinse each surface.
- Apply an approved food-contact sanitizer.
- Leave it on for the stated contact time.
- Rinse if required by the product instructions.
- Dry the board completely.
FoodSafety.gov recommends using separate cutting boards for raw meat, poultry, and seafood and for produce or food that will be eaten without further cooking. It also advises washing boards with hot soapy water after contact with raw animal products.
Separate boards make cross-contamination easier to control, especially in professional kitchens or busy homes. Different colors or sizes can help you identify each board at a glance.
The antibacterial treatment in the rubber doesn’t replace washing or sanitation. Think of it as an extra layer of support, not a substitute for cleaning.
Can You Pour Boiling Water Over a Parker Asahi Cutting Board?
Heat limits vary between Parker Asahi product lines. As a general rule, keep routine cleaning below 90°C unless the instructions for your exact model state otherwise.
| Parker Asahi board type | Published heat guidance | Recommended approach |
|---|---|---|
| Professional / PRO board | Do not use or store above about 90°C | Use warm water for everyday cleaning |
| Household / Consumer board | Listed as resistant up to about 100°C | Brief hot-water sanitation may be allowed |
| All models | Not dishwasher-safe | Wash by hand |
Professional board instructions give an operating and storage limit of about 90°C. Some household boards are listed as resistant to temperatures near 100°C, but the manufacturer still warns against boiling-water immersion and prolonged heat exposure.
To reduce the risk of warping:
-
don’t place the board in a pot of boiling water;
-
don’t soak it in very hot water;
-
don’t pour boiling water onto one small section;
-
treat both sides evenly if you use hot water;
-
let the board cool on a flat surface;
-
never place a hot pan directly on it.
The key problem is often uneven heat. One hot spot can expand while the rest of the board stays cool, a little like pulling one corner of a sheet while the other corners remain fixed.
If you don’t know which model you have, use warm soapy water and a food-safe sanitizer instead of boiling water.
Quick answer: Check the care instructions for your model. A heat-resistant board can still warp if heat is concentrated in one area or applied for too long.
How Do You Remove Stains and Odors from a Parker Asahi Board?
Treat fresh stains and odors as soon as possible. Start with dish soap. Use diluted bleach for marks that remain, and resurface the board only if discoloration has settled into shallow knife cuts.
Begin with the mildest method.
Step 1: Wash the Area Immediately
Fish oils, grease, spices, and vegetable pigments become harder to remove once they dry. Wash the board as soon as you finish preparing food.
Step 2: Clean the Whole Board
Don’t scrub one small area excessively. Wash the top, bottom, and edges so moisture and surface wear remain reasonably even.
Step 3: Sanitize Persistent Stains
After normal washing, apply a correctly diluted bleach solution for a short period. Rinse the board and let it dry fully.
Step 4: Resurface Marks That Remain
If the stain sits inside shallow knife marks, remove a very thin layer of the surface with a cutting board scraper or waterproof sandpaper.
The Fuchioka MS-83 Cutting Board Scraper, 2-Pack is made specifically for the maintenance of Parker Asahi synthetic cutting boards. Its abrasive surface helps remove discoloration, food residue, and knife marks without relying on aggressive cleaning chemicals.
Black Parker Asahi boards hide pigment stains more effectively than beige boards, but they need the same cleaning and sanitation routine.
A permanent stain doesn’t always mean the board is unsafe. If you have cleaned and sanitized the surface correctly, the discoloration may be cosmetic. Deep or rough grooves that hold food residue are a different matter and should be repaired or assessed carefully.
How Do You Remove Knife Marks and Scratches?
You can remove shallow knife marks with a dedicated cutting board scraper or waterproof sandpaper of around #100 grit. Work under running water and move along the longest side of the board.
Parker Asahi boards resist cutting damage well, but every cutting surface eventually shows signs of use. Knife marks are normal wear, not automatically a product defect.
For regular surface maintenance, the Fuchioka MS-83 scraper is a practical option. The set contains two scrapers made for Parker Asahi synthetic rubber boards. It allows you to refresh worn areas mechanically and remove a very thin surface layer where stains or knife marks have become trapped.
Use the following method:
- Wash the board first. Remove grease and food residue before resurfacing.
- Place it on a stable surface. Work beside a sink or under gently running water.
- Wet the board and scraper. Water reduces friction and helps carry away loosened particles.
- Move along the length of the board. Use long, even strokes rather than short circular movements.
- Apply light, steady pressure. Let the abrasive surface do the work.
- Remove as little material as possible. Stop once the stain, mark, or rough area has disappeared.
- Blend the repaired section. Extend your strokes slightly beyond the damaged area so you don’t create a visible hollow.
- Wash the board again. Remove rubber residue and abrasive particles.
- Dry it completely. Check that the surface feels even before using it for food preparation.
Don’t use the scraper like a heavy-duty sanding tool. Several light passes are safer than one aggressive pass. The aim is to refresh the surface, not carve into it.
If you don’t have a dedicated scraper, Parker Asahi also recommends waterproof sandpaper of around #100 grit. Use it under running water and work along the long side of the board.
Avoid metal files, powered sanders, and very coarse abrasives. These tools can remove too much material too quickly and leave the board uneven.
The Fuchioka MS-83 can extend the useful life of the board by removing surface wear before grooves become too deep to clean. Regular use doesn’t mean frequent use, though. Reach for the scraper only when ordinary washing and sanitation no longer remove the marks.
Quick answer: Use a Fuchioka MS-83 scraper or #100 waterproof sandpaper for stains and shallow knife marks that normal washing cannot remove. Work wet, move along the length of the board, and remove only a thin surface layer.
How Should You Store a Parker Asahi Cutting Board?
Store the board completely flat or perfectly vertical. It should have even support and no sideways pressure. Never leave it leaning diagonally against a wall or cabinet.
Synthetic rubber can slowly take on a curved shape if it remains at an angle, especially in a warm kitchen.
The risk increases when the board is:
- stored near an oven or radiator;
- left beside a hot professional range;
- exposed to direct sunlight;
- supported at only one corner;
- pressed under uneven weight;
- stored damp between other boards;
- left leaning for long periods.
For vertical storage, use a rack that holds the board straight. Thick professional boards are heavy, so the rack must support their weight without bending the lower edge.
For horizontal storage, place the board on a flat, dry surface. Don’t leave a hot pan, heavy appliance, or other weight on one section.
A board left leaning for months may slowly take on that shape. It’s a bit like a book stored under pressure: the change is gradual, but eventually it becomes difficult to ignore.
Parker Asahi warns that angled storage may cause bending or warping. Flat storage or straight vertical storage is safer.
Can a Warped Parker Asahi Cutting Board Be Flattened?
A slightly warped professional Parker Asahi board may sometimes be corrected with controlled heat, a flat surface, and evenly distributed weight. Prevention is still safer than repair.
Published instructions for compatible professional boards describe this process:
- Warm the board evenly to about 80°C.
- Place it on a completely flat, heat-resistant surface.
- Distribute weight evenly across the board.
- Leave it in place until the board has cooled fully.
This method is intended for certain types of heat-related deformation in professional boards. Don’t use an oven, direct flame, or a temperature above the board’s stated limit.
Don’t attempt this repair if the board is cracked, badly twisted, or made from an unknown material. Thin Consumer and Black boards may react differently from thick professional models.
If the board rocks slightly, check the countertop first. A food scrap, droplet of water, or uneven worktop may be the real cause.
Does a Parker Asahi Cutting Board Need Oil?
No. Don’t apply mineral oil, cooking oil, wax, or wooden cutting board conditioner to a Parker Asahi rubber board.
Oil protects wooden boards by slowing moisture absorption and reducing the risk of cracking. Synthetic rubber has no wood grain and gains nothing from this treatment.
Oil can instead:
- make the cutting surface slippery;
- attract dust and food particles;
- make cleaning harder;
- create unwanted odors;
- transfer onto food;
- reduce grip on the countertop.
A dry or slightly faded appearance after washing doesn’t mean the board needs conditioning. Let it dry fully and continue with the normal cleaning routine.
What Can Damage a Parker Asahi Rubber Cutting Board?
The most common causes of avoidable damage are excessive heat, dishwasher use, angled storage, prolonged chemical soaking, and unsuitable cutting methods.
Avoid:
- dishwashers and heated dish dryers;
- direct flame;
- hot pots and baking trays;
- prolonged boiling-water immersion;
- storage above about 90°C;
- leaving the board at an angle;
- placing heavy objects on one area in a warm room;
- soaking it in concentrated bleach;
- using metal scourers for daily cleaning;
- using powered sanding tools;
- chopping bones with heavy cleavers;
- cutting frozen food;
-
dragging serrated blades aggressively across the surface.
A Parker Asahi board is made for normal kitchen knife work. It shouldn’t be used as a trivet, heat shield, workshop mat, or bone-chopping block.
The cutting surface also affects the life of your knife edge. Our guide to caring for a Japanese kitchen knife explains how cutting technique, washing, storage, and sharpening influence sharpness.
How Often Should You Perform Each Maintenance Task?
Wash the board after every use. Sanitize and resurface it only when its condition or use makes those steps necessary.
| Maintenance task | Recommended frequency |
|---|---|
| Wet the surface before cutting staining ingredients | Before each relevant use |
| Wash with dish soap | After every use |
| Wash the underside and edges | After every use |
| Sanitize after raw meat, poultry, fish, or seafood | After each relevant use |
| Check for trapped residue | During every wash |
| Check for warping | Every 2–4 weeks for boards used daily |
| Treat stains with bleach | When normal washing is not enough |
| Use the Fuchioka MS-83 scraper | When stains or shallow marks remain after cleaning |
| Resurface with #100 waterproof sandpaper | Only when permanent marks or rough grooves appear |
| Oil or wax the board | Never |
| Use a dishwasher | Never |
Inspect a board used every day about once a month. Run clean fingertips over the dry surface and look at it under angled light. Rough grooves may hold residue even if they are hard to see from above.
The Fuchioka MS-83 shouldn’t become part of your daily washing routine. Use it as a maintenance tool when the surface begins to show stubborn discoloration, rough patches, or shallow grooves that ordinary cleaning cannot remove.
When Should You Replace a Parker Asahi Cutting Board?
Replace the board if it develops structural damage or deep grooves that can no longer be cleaned or resurfaced safely.
A replacement may be necessary if:
- the board is cracked;
- it remains badly warped after cooling flat;
- it rocks during cutting;
- deep grooves continue to trap residue;
- repeated resurfacing has made the surface uneven;
- parts of the material begin to separate or deteriorate;
- odors remain after cleaning and sanitation;
- excessive heat has damaged the board;
- further resurfacing would make it too thin or unstable.
Normal cosmetic marks aren’t a reason to throw the board away. One of Parker Asahi’s main advantages is that the surface can be refreshed several times, unlike many thin plastic boards.
A dedicated scraper such as the Fuchioka MS-83 can help delay replacement by removing worn surface material before shallow marks develop into deeper grooves. Still, there is a limit. If the board is cracked, unstable, or heavily deformed, resurfacing won’t make it safe again.
A Simple Maintenance Routine Protects the Board and Your Knives
Parker Asahi rubber cutting boards don’t need oil, wax, or seasonal conditioning. Good maintenance comes down to five habits:
- Wet the surface before cutting ingredients that may stain.
- Wash the top, bottom, and edges immediately after use.
- Sanitize the board after preparing raw meat, poultry, fish, or seafood.
- Dry it fully before storage.
- Keep it away from dishwashers, high heat, and angled storage.
Resurface shallow stains and scratches only when washing no longer removes them. The Fuchioka MS-83 Cutting Board Scraper offers a simple way to refresh the surface without using strong chemicals. Waterproof sandpaper of around #100 grit is another option when used carefully.
Whichever tool you choose, work slowly. Remove only the damaged surface layer and keep the repaired area even with the rest of the board.
A knife-friendly cutting board also helps protect the thin edge of a Japanese kitchen knife. Browse our Parker Asahi cutting boards in sizes suited to compact home kitchens and larger professional workstations, or explore our full selection of Japanese knives.

Frequently Asked Questions About Parker Asahi Cutting Board Care
Are Parker Asahi Cutting Boards Dishwasher-Safe?
No. Parker Asahi recommends hand-washing because dishwasher heat and heated drying can warp or deform the synthetic rubber.
Can You Use Bleach on a Parker Asahi Board?
Yes. You can use diluted household bleach for sanitation and persistent stains. Wash the board first, follow the sanitizer’s contact time, rinse it thoroughly, and dry it. Don’t leave it soaking for a long period.
Do Parker Asahi Rubber Boards Need Mineral Oil?
No. Synthetic rubber doesn’t need mineral oil, wax, or board cream. These products are intended for wood and may leave a rubber board slippery or harder to clean.
Why Should You Wet the Board Before Using It?
A thin layer of clean water reduces direct contact between the surface and strongly colored, oily, or aromatic food juices. Wet the board, then wipe away the excess before cutting.
What Is the Fuchioka MS-83 Cutting Board Scraper Used For?
The Fuchioka MS-83 is used to remove surface stains, discoloration, food residue, and shallow knife marks from Parker Asahi synthetic cutting boards. Wet the board and scraper, then work along the length of the surface with light, even pressure.
How Often Should You Use the Fuchioka MS-83 Scraper?
Use it only when normal washing and sanitation no longer remove stains, rough patches, or shallow knife marks. It isn’t needed after every use.
How Do You Remove Black Marks or Deep Stains?
Wash and sanitize the board first. If marks remain inside shallow cuts, use the Fuchioka MS-83 scraper or waterproof sandpaper of around #100 grit under running water. Work along the length of the board and remove as little material as possible.
Can You Put a Hot Pan on a Parker Asahi Cutting Board?
No. The board may resist heat within its stated temperature range, but concentrated heat from a pan can deform or damage the rubber. Use a proper trivet instead.
Should a Parker Asahi Board Be Stored Flat or Upright?
Both methods are safe if the board has full support. Store it flat on a level surface or perfectly vertical in a suitable rack. Don’t leave it leaning at an angle.
How Long Does a Parker Asahi Cutting Board Last?
There is no fixed replacement date. Its lifespan depends on how often you use it, how you cut, how you clean it, and how many times you resurface it. Keep using the board while it remains flat, stable, intact, and easy to clean.
