How to Care for Wooden Utensils: Wash, Dry, and Oil in 4 Steps
John Boos says wood boards are not dishwasher safe and should be oiled at least monthly. See the wash, dry, oil, and sanitize routine in 4 steps.

Wooden spoons, spatulas, and cutting boards can last for years with a small routine: wash by hand, dry standing up, and oil about once a month. Wood swells and shrinks with moisture, so every care rule serves one goal, which is keeping the moisture balanced. This guide follows the care instructions from John Boos and sanitizing guidance from the USDA.
Wash by hand after every use
Wash wooden utensils with hot, soapy water after each use. Rinse well and move on to drying right away. Wood does not belong in the dishwasher: John Boos states plainly that wood cutting boards are not dishwasher safe. A long hot cycle soaks the wood and the drying cycle heats it, which is the quickest route to cracks and warping.
Do not soak or submerge wood either. The manufacturer says soaking disrupts the moisture content and can cause the rails to split. A quick wash and a quick dry is the safer routine. The care schedule below puts the whole routine in one place.
| Task | How | How often |
|---|---|---|
| Wash | Hot soapy water | After each use |
| Dry | Stand on end, air dry | Every time |
| Oil | Even coat, overnight | Monthly |
| Sanitize | 1 tsp bleach / quart | As needed |
What the table shows: washing and drying are daily habits, oiling is a monthly appointment, and sanitizing is for the moments when raw meat or heavy use calls for it.
Dry standing up
How wood dries matters as much as how it is washed. John Boos says it is best to dry a board standing up, in an upright position, instead of laying it down. That lets air reach both faces so one side does not stay damp. You can also wipe the piece with a clean paper towel first, then let it air dry.
Utensils dry fastest with airflow around them, so a utensil crock or an open rack works better than a closed drawer. If a spoon or board still feels damp, give it more time before the next step. Oil applied over damp wood can trap moisture inside, which defeats the purpose.
Oil once a month with the right oil
John Boos recommends oiling a minimum of once a month, depending on use and household conditions. Apply an even coat to the surfaces with a cloth or towel. Let the oil soak in for at least 3 to 4 hours, or preferably overnight, then wipe off the extra in the morning.
Re-oil sooner if the wood looks dry. A dry board often looks lighter in color, which is a simple visual cue that it is ready for another coat.
The oil choice matters. The manufacturer says to use only its Mystery Oil or Board Cream when oiling a cutting board, and it names plain mineral oil as a quick alternative. It prints the warning in capitals: do not use any type of cooking oil on wood cutting boards. A board cream adds an extra layer of protection from moisture and food odors, and it goes on with circular motions before the excess is wiped off.
Sanitize and separate
For a deeper clean, John Boos gives two options: one teaspoon of liquid chlorine bleach in one quart of water, or a one to five dilution of vinegar. The USDA's guidance for cutting boards is close to the bleach option. It says to flood the surface with one teaspoon of unscented liquid bleach per quart of water, let it stand for ten minutes, rinse with clean water, and then let it air dry or pat it dry with fresh paper towels. The USDA adds that there is no advantage to using more bleach.
Separation is the other half of kitchen food safety. A common practice is to keep one board for raw meat, poultry, and fish, and another for cooked or ready-to-eat foods such as salad, vegetables, and bread. A small label or a different wood tone makes the division easy to remember in a busy kitchen.
| Option | Mix | Contact time |
|---|---|---|
| Bleach (John Boos) | 1 tsp per quart of water | See product label |
| Bleach (USDA) | 1 tsp unscented per quart | 10 minutes, then rinse |
| Vinegar (John Boos) | 1 part vinegar to 5 parts water | See official site |
What the table shows: the bleach ratios from the two sources match, and the USDA adds the standing time and the rinse step.
Follow these steps
- After each use, wash with hot soapy water, rinse, and stand the piece on end to air dry completely. Skip the dishwasher and the soak.
- Once a month, apply an even coat of food-grade mineral oil or the maker's oil, let it soak in overnight, and wipe off the excess. Re-oil sooner if the wood looks dry and lighter.
- Sanitize with the bleach-water or vinegar solution after raw meat contact or heavy use, and keep separate boards for raw and ready-to-eat foods.
- Keep cooking oils in the pantry, since the maker says not to use them on wood.
Before you buy
If you are setting up the routine from scratch, you need two things: a food-grade mineral oil made for wood, and optionally a board cream for extra protection. Check that the label says food-grade, and choose a product whose directions match the monthly routine above.
When comparing oils, the spec that matters is the label: a food-grade mineral oil base, no cooking-oil content, and directions you can follow. Keep the bottle in a cool cabinet away from the stove. See official site pages from the maker for current product details.
