To disinfect a cutting board, wash it with hot, soapy water right after use, apply a sanitizer approved for food-contact surfaces exactly as its label directs, then dry the board completely. That routine works for wood and plastic alike. The difference is the dishwasher: a plastic board can go through it, a glued-up wood board should not. Never mix cleaning chemicals, and do not treat vinegar or household hydrogen peroxide as a validated sanitizing step. The drying step is not optional, because moisture left in the wood gives bacteria and mold what they need.
When the board is dry, Board Balm Cutting Board Conditioner holds the oil. Our 17ร13ร1.75 end-grain maple board is finished the same way.
Cleaning and disinfecting are not the same thing, and the difference matters after you cut raw chicken. Cleaning removes visible food and grease. Sanitizing is an additional risk-reduction step after cleaning, especially after raw meat or poultry. You do the first every time and the second when you have handled raw protein. Here is how to do the second without wrecking the board in the process.

Key takeaways
- Wash first with hot soapy water, then use a food-contact-surface sanitizer exactly as its label directs, then dry fully.
- Plastic boards can go in the dishwasher; glued-up wood boards should not.
- Never mix cleaning chemicals, and do not count on vinegar or household peroxide as a validated sanitizing step.

Key takeaways
- Wash with hot, soapy water after every use, rinse with clear water, then air dry or pat dry (USDA FSIS).
- FSIS says both wooden and plastic boards can be sanitized with "1 tablespoon of unscented, liquid chlorine bleach per gallon of water": flood the surface, let it stand for several minutes, then rinse with clear water and air dry or pat dry (USDA FSIS). For a Bevel & Bond board, follow our care instructions, which say not to use bleach on it.
- Never put a wooden board in the dishwasher. FSIS says solid wood boards can be washed in one but that laminated boards may crack and split, and an end-grain board like ours is glued up from many blocks; our care instructions add that heat and prolonged moisture will warp and crack the board permanently. Never leave a wood board soaking either (can you put a wooden cutting board in the dishwasher).
- Once it is fully dry, re-oil the board.
What is the best way to disinfect a wooden cutting board?
There is no single best household disinfectant for every wooden board. Use a food-contact-surface sanitizer according to current official guidance and its label directions. After washing, follow the selected food-contact-surface sanitizer's label directions for concentration, contact time, rinsing, and drying. Household hydrogen peroxide should not be presented as a universally validated substitute for labeled food-contact-surface sanitizers.

White vinegar is fine for everyday cleaning and may help with odors, but it should not be presented as a validated replacement for a labeled food-contact-surface sanitizer. You may also see vinegar and hydrogen peroxide recommended as a pair. That idea traces back to work by food scientist Susan Sumner at the University of Nebraska and Virginia Tech in the mid-1990s, which reported the two mists together killed far more bacteria on produce and surfaces than either alone (Peters, Sumner, Albrecht and Bullerman, 1996). It is one line of research from thirty years ago, not current food-safety guidance, so do not rely on it in place of a labeled sanitizer, and never mix cleaning chemicals. Whatever you use, the wash comes first and the full dry comes last. The routine cleaning half of this is covered in how to clean a wooden cutting board.

| Method | Role | Wood-use note |
|---|---|---|
| Warm water and dish soap | Routine cleaning | Scrub, rinse, and dry promptly |
| Labeled food-contact-surface sanitizer | Sanitizing when appropriate | Follow the product label and current official guidance |
| White vinegar | Everyday cleaning and odor control | Not a substitute for a validated sanitizer |
| Salt and lemon | Surface freshening | Not a sanitizing step |
| Dishwasher or soaking | Not suitable for wood | Heat and prolonged moisture can damage the board |
How do you disinfect a plastic cutting board?
Wash it in hot, soapy water or run it through the dishwasher, then sanitize it with a bleach solution after raw meat. The USDA Food Safety and Inspection Service gives 1 tablespoon of unscented liquid chlorine bleach per gallon of water: flood the surface, let it stand for several minutes, rinse with clear water, then air dry or pat dry with clean paper towels. Check the label on your bottle, because the concentrated 8.25% bleach sold today is stronger than the older 5.25% formula.
Plastic has one weakness that no amount of bleach fixes: knife scars. Once a plastic board is covered in deep grooves, hot water and sanitizer struggle to reach the bottom of them, and FSIS says boards with hard-to-clean grooves should be thrown out. A $12 plastic board scored white after a year of use is a replacement job, not a cleaning job.
| Step | Wood board | Plastic board |
|---|---|---|
| Everyday wash | Hot, soapy water by hand | Hot, soapy water or the dishwasher |
| Sanitize after raw meat | Labeled food-contact sanitizer, or diluted bleach at the ratio below, then rinse | 1 tablespoon unscented bleach per gallon (USDA FSIS), then rinse |
| Dishwasher | No. Heat and soaking crack glued-up boards | Yes |
| Drying | Towel dry, then stand on edge | Air dry or pat dry with paper towels |
| Replace when | Cracks or grooves you cannot sand out | Deep, hard-to-clean knife grooves |

How do you disinfect a cutting board after raw chicken?
After raw chicken, wash the board immediately with hot, soapy water. When sanitizing, follow current USDA guidance and the label directions for a sanitizer approved for food-contact surfaces, including concentration and contact time. Do not let the board sit with raw poultry residue while you cook, wash it right away, because bacteria multiply on a wet, soiled surface. Clean all contacted surfaces thoroughly, then follow the selected food-contact-surface sanitizer's label directions. Towel dry promptly and allow adequate airflow on both sides. For the full routine after raw chicken, see how to clean a cutting board after raw chicken.
The smarter long-term habit is to keep a dedicated board for raw protein so you never cross-contaminate produce or bread. If that dedicated board is plastic, use the plastic method above; if it is wood, use the steps here. We cover the cross-contamination case in separate cutting boards for meat and vegetables, and the wood-versus-plastic safety question in are wooden cutting boards sanitary.
Can you use bleach to disinfect a wood cutting board?
You can, but you should not make it your default, and the ratio depends on which bleach is under your sink. The concentrated 8.25% bottles that replaced the old 5.25% ones changed the math, so the single number you may have memorized is probably wrong now. Michigan State University Extension puts the target for food-contact surfaces at 50 to 100 ppm available chlorine, which works out to 1 teaspoon of 8.25% bleach per gallon of water, or 2 teaspoons of 5.25 to 6.25% bleach per gallon. Check the label on your bottle, and use chlorine test strips if you want to be sure.
Even mixed correctly, bleach is harsher than a wood board needs. It can discolor the wood, raise and roughen the grain, and leave a residue and smell you then have to rinse thoroughly. Vinegar and household hydrogen peroxide should not be assumed to provide the same validated sanitizing performance as a labeled food-contact-surface sanitizer. If you do use bleach after something high-risk, keep it at the ratio above, rinse the board well, dry it completely, and re-oil it afterward to restore the surface the bleach dried out. For routine disinfecting, skip it. Never use full-strength bleach on wood. If bleach has already left the surface rough or blotchy, a light sanding resets it; here is how to refinish a cutting board.
For the full method, see our guide on how to get smell out of a wood cutting board.
What sanitizer concentration (ppm) should you use on a cutting board?
For chlorine bleach, aim for 50 to 100 ppm of available chlorine, the range Michigan State University Extension gives for food-contact surfaces; the bleach ratios in the answer above land you inside it. A stronger mix adds no useful safety margin on a board. It just bleaches the wood, roughens the grain and leaves more residue to rinse away. Chlorine test strips from a restaurant supplier show the actual reading in a few seconds, which is the only way to know what your bottle delivers. Any other sanitizer, such as a quaternary ammonium product, has its own validated ppm and contact time on the label: mix it to that number, keep the surface wet for the full contact time, rinse only if the label says to, then dry the board on edge.
For the full method, see our guide on how to remove stains from a wood cutting board.
Does the dishwasher disinfect a cutting board?
The dishwasher does disinfect through heat, but it destroys wood boards in the process, so it is never the right choice for one. The prolonged soak and high heat flood the wood with moisture and then bake it, which causes warping, cracking, and split glue joints. You would trade a clean board for a ruined one. Plastic boards can go in the dishwasher; wood boards cannot. If you have already run yours through, our guide on why cutting boards warp covers the damage and recovery.
Want a board that is easy to keep sanitary?
The Bevel & Bond End-Grain Maple Cutting Board is dense, closed-grain hard maple sealed with Board Balm, so it sheds water, dries fast, and gives bacteria the least possible foothold. A conditioned, tight-grained board is far easier to disinfect and dry than a dry, cracked, open-grain one. Keep it sealed and it does much of the hygiene work for you.
Does salt disinfect a cutting board?
No. Coarse salt can help lift odor and light residue, but it is not a validated sanitizing or disinfecting step. After raw protein, wash thoroughly and, when sanitizing is appropriate, follow current official guidance and the label directions for a sanitizer approved for food-contact surfaces.
How often should you disinfect a wooden cutting board?
Disinfect after every contact with raw meat, poultry, or fish, and otherwise a normal hot-soapy-water wash is enough for produce and bread. You do not need to chemically disinfect a board you only used to slice vegetables; washing and drying handles that. For higher-risk jobs, use a sanitizer approved for food-contact surfaces according to current official guidance and label directions. Over-disinfecting a produce-only board just dries the wood out faster without a safety benefit.
Do you need to oil the board after disinfecting it?
Not every time, but disinfecting agents and repeated washing strip the board's oil, so re-oil whenever the surface starts to look or feel dry. Peroxide and vinegar are water-based and will pull some conditioning out of the wood over time. Keeping a broken-in board oiled monthly, or every 2 to 3 weeks in dry winter air, keeps it sealed, which in turn keeps it easier to disinfect and quicker to dry. Use food-grade mineral oil or Board Balm Cutting Board Conditioner, and see the oiling guide for the routine.
Can you use vinegar and hydrogen peroxide together?
Not as a substitute for a labeled sanitizer. Never mix them in one bottle: combined, they form peracetic acid, which irritates skin, eyes and lungs. A study conducted under specific conditions does not validate the method for every household board, concentration, contact time, or food-safety situation. If a job calls for sanitizing, use a sanitizer approved for food-contact surfaces and follow its label.
Is a wooden cutting board harder to disinfect than plastic?
A little. USDA FSIS says nonporous surfaces such as plastic are easier to clean than wood, but it also says wooden and plastic boards can both be sanitized with the same diluted bleach solution (USDA FSIS, checked October 18, 2026). Condition matters more than material: FSIS says boards that are excessively worn or have hard-to-clean grooves should be thrown out.
Everyday cleaning in brief
- Scrub with hot water and a little dish soap right after use.
- Rinse; don't soak it or put it in the dishwasher.
- Towel it off and stand it on edge to dry.
When was this article last reviewed?
This guide was last reviewed in October 2026, when we added the plastic cutting board method from USDA Food Safety and Inspection Service guidance. The recommendations here prioritize official food-safety guidance and labeled use instructions for food-contact surfaces.
What is the simplest routine to disinfect any cutting board?
Wash first, sanitize with a labeled food-contact sanitizer when the job calls for it, and dry the board fully on edge. That approach supports safer handling after raw meat while protecting the board from soaking and dishwasher exposure. Never put a wooden board in the dishwasher. If using a properly diluted bleach solution or another sanitizer, follow current USDA guidance and the product label exactly. Keep the board oiled so it stays sealed and easy to clean. The Bevel & Bond End-Grain Maple Cutting Board is built to make all of this easy, and it pairs with Board Balm Cutting Board Conditioner to stay sealed.
