Wood Cutting Board Care Guide

Caring for Your End-Grain Cutting Board

End-grain boards are built to last decades — but only if you treat them right. A few simple habits will keep your MNCWOOD board performing like new for generations.

Daily Use

Wipe clean after each use. Warm water, a soft sponge, mild dish soap. Rinse thoroughly and dry with a clean towel.

Never soak. Do not leave your board submerged in water or sitting in a sink. Wood absorbs water and will warp or crack.

Not dishwasher safe. The high heat and prolonged moisture of a dishwasher will destroy any wooden board. Hand wash only.

Dry standing up. After washing, stand the board on its edge so air can circulate on both sides. This prevents warping.

Monthly Maintenance

Every 3–4 weeks — or whenever the wood starts to look dry — apply food-safe mineral oil:

  1. Make sure the board is clean and completely dry.
  2. Pour a generous amount of food-grade mineral oil onto the surface.
  3. Rub into the wood with a clean, lint-free cloth, following the grain.
  4. Let it absorb for a few hours or overnight.
  5. Wipe off any excess oil.

For extra protection, follow up with a board butter (a blend of mineral oil and beeswax). Apply the same way.

Do not use:

  • Olive, vegetable, or any cooking oils — they turn rancid.
  • Varnish, polyurethane, or wood sealer — not food safe.
  • Hardware-store linseed or tung oil — may contain drying agents.

Removing Stains and Odors

For light stains or garlic/onion smells: sprinkle coarse salt, rub with half a lemon, rinse, and dry.

For deeper discoloration: sand lightly with fine-grit sandpaper (220+) along the grain, then re-oil generously.

What to Avoid

  • Cutting frozen food. Will dent or crack the surface.
  • Raw meat for extended sessions. Use a designated board, or wash thoroughly with hot soapy water straight after.
  • Hot pots or pans on the board. Wood is heat-sensitive — it can scorch or split.
  • Rapid humidity changes. Don't store near a radiator, oven, or sunny window.

Expected Wear

Wooden boards develop character over time. Small knife marks, subtle color shifts, and the occasional hairline check in the end grain are normal — they're signs of a board that's being used. End-grain boards "self-heal" to some extent: wood fibers close back around the knife edge, which is why they keep their looks longer than face-grain boards.

Restoring a Neglected Board

If your board looks gray, dry, or rough:

  1. Sand the entire surface with 120 grit, then 220 grit.
  2. Wipe off all dust with a slightly damp cloth.
  3. Let dry fully (4–6 hours).
  4. Apply mineral oil every few hours over one full day until the wood stops absorbing.
  5. Finish with board butter.

With this routine, your MNCWOOD board will outlast the kitchen it came into.
