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.

Heat the board up with a paint-stripping heat gun, and boil the mineral
spirits off.

This can be done as a part of the process of saturating the wood surface with
mineral oil, on say a butcher block countertop: Cover the wood surface with
heavy mineral oil from a drugstore (this oil is edible). Heat oiled surface
with the heat gun. Add oil as needed to keep the surface uniformly wet. The
oil will appear to boil as water is boiled off and air is expelled by the
heat. When the oil begins to smoke, stop and allow things to cool. The
surface oil will be drawn into the wood grain. One can repeat the process
once or twice to ensure full saturation of the surface.

I did this 17 years ago in my kitchen. Still holding up.
