Last year, I bought some small cutting boards from a friend. I took them home and sanded them and then used mineral spirits to clean them up. I knew it was wrong and I've not distributed them as gifts as I intended last year. Just wondering, how do I "fix" them to make sure that my friends and family don't get sick.

I was thinking of resending, then flooding them with mineral oil, letting them try and then doing it again.

Any hints would be helpful.
