A good acacia cutting board isn't disposable. Treat it right and it outlives a decade of the plastic ones you keep throwing away.
The short version: hand wash after every use, towel dry and stand it upright, and rub in a food-safe oil about once a month. Below, the full routine step by step, the best oil to use, and the four mistakes that ruin a wood board.
Why it matters
Wood is alive, a little care keeps it that way
Acacia is a dense hardwood, but it's still natural material. Water and heat are its only real enemies: left wet or dried out, any wood board can eventually warp or develop surface cracks. A quick wash and the occasional coat of oil keep the grain sealed, water-resistant and beautiful for years.
The routine
How to clean and oil a wood cutting board, step by step
Wash by hand, right after use
Warm water, a little dish soap, a soft sponge. Give both sides a quick scrub and rinse. Don't let food dry on the surface, and never leave the board soaking in the sink.
Towel dry, then air dry upright
Pat it dry with a towel, then stand it on its edge so both faces dry evenly. Drying flat on the counter traps moisture underneath, the main cause of warping.
Oil it about once a month
Pour a little food-safe oil (food-grade mineral oil, or a board cream) onto the dry board and rub it in with a cloth. Coat every side, including the edges. Let it soak in for a few hours, overnight is ideal.
Buff off the excess
Wipe away anything that hasn't absorbed with a clean cloth. The board should feel rich, not greasy. That's it, back to work.
How often, really?
Once a month is the sweet spot for a board in regular use. A quick test: flick a few drops of water onto the surface. If they bead up, you're good. If the wood drinks them in and darkens, it's thirsty, time to oil.
One thing about end-grain boards
An end-grain board is thirstier than a flat one: with the fibres standing upright, the surface drinks oil deeper and more evenly. Give a new board two or three coats over its first couple of weeks, and it will reward you with a surface that stays sealed and rich for years.

Care is easy when the board is built to take it
Thin bamboo and softwood boards fight you: they dry out, crack and splinter, and no amount of oil brings them back. A dense end-grain acacia board is the opposite. The thickness keeps it stable, the hardwood shrugs off moisture, and the upright grain takes oil beautifully, so ten minutes a month is genuinely all it asks.

Frequently asked questions
What is the best oil for a cutting board?
Food-grade mineral oil, or a dedicated board cream (often mineral oil with beeswax). Avoid cooking oils like olive or vegetable, they turn rancid in the wood. BoardMere Wood Care Oil is food-grade mineral oil made for exactly this, currently 50% off at $24.99.
How often should I oil an acacia cutting board?
About once a month with regular use. If water no longer beads on the surface, it's time. New boards benefit from a couple of coats in the first few weeks.
Can I put an acacia board in the dishwasher?
No. The heat and prolonged water will warp and crack it. Hand wash, towel dry, and stand it upright to finish drying.
