Borax is always really wonderful for removing mold. I had a basket made out of bamboo wood and it became moldy for the same reason your cutting board did, and after an application of borax and water it was mold-free! Also, borax helps prevent the re-growth of mold. Try soaking the board in a mixture of borax and water, but remember to oil the board when you are done because this isn't good for the wood!

The product is called sol-u-mel--it is the highest grade of tea tree oil {essential oil} one of it's properties is an anti-fugal thus after several treatments {it is penatrating will work} I know Deb is not a huge fan however this has helped lot's of children with mold and mildew allergies, as well as the removal!!

I want to thank everyone who responded to my plea for help about the mold on my cutting board. If I ever get so careless again I'm going to try to borax method I think. I needed to move faster than the speed of light (it's my main board) so I called the John Boos Company that morning and they said get the sander out and just sand the spot out; that it probably wasn't that deep. They were correct. It came right out as well as some of the cut marks.

So I went over the whole thing with vinegar to clean it up properly, rinsed well, air dried, then oiled it with (sorry) mineral oil (didn't have any walnut oil yet) and I'm good to go for now. (Sigh of Relief)

Thank You All So Much. Debra, This is a GREAT Website. I'm really impressed. I'm telling all my friends about it. I'm a grandmother 7 times over with a good deal of experience, and a really appreciate a resource like you and your readers and providing to the rest of us. This is what the internet should be.

To disinfect bacteria laden cutting boards, I use diluted GrapeFRUIT seed extract.

Hydrogen peroxide works well. Let it sizzle for around 5-10 minutes first. A more concentration solution than 3% might help, but I don't really know.
