Got pictures of how bad it is? Do you know what it’s glued with? What oil it was originally covered with?

The first thing I would try is to kill the mold by placing it in the oven for a few hours at 180°-212° for several hours.
that is, if the finish and the glue will handle it.

Next, after killing the mold, scrub like the dickens with Clorox and a 3M pad.

Hydroden peroxide kills mold and so does household bleach. I’m guessing you need to both kill the mold and sand to remove discoloration. Is it valuable enough or a family heirloom that you want to take on the health risk associated with a botched restoration?

A porous, moldy food prep surface sounds nasty and I wouldn’t take the risk of trying to return it to a healthy state. Personally, I would throw it away and not risk it.

You might be able to cut a quarter inch or so off with a BS and start with a clean slate so to speak.

Give it a “Bleach Bath”.
One cap Bleach per gallon of Water, let it soak for a while…
Rinse and wipe well (Air-dry even better)... It should be good to go!

Bleach and peroxide kills surface mold. Mold has micrscopic tendrils, like roots, that bury into the surface of porus material like wood. It can come back even after a chemical treatment.

A good scrubbing with borax and a wire brush is just as effective any any other treatment I have tried; and I have tried many. And it seems to last longer than clorox and peroxide.

The only method that I am aware of to permanently kill mold is with heat, as has already been suggested.

1. Rent a power washer
2. Place cutting board on you back deck.
3. Power-wash the cutting board, along with your entire deck while you’re at it…If you hold it close enough, it will remove mold from both, along with the top layer of wood.
4. Go pick up the cutting board after it flies across the yard.
5. When this doesn’t work, use one of the suggestions from other Lumberjocks.

-- I'm strictly hand-tool only...unless the power tool is faster and easier!
