My wife brought home a very used butcher block table from a garage sale.
After an all-day session with the sander and scraper, the thing looked
pretty good. Sent the wife off to the hardware store to get a food-grade
finish for it. I was expecting a drying oil, which I've used many times
before, but what she brought home was mineral oil, and I was tired and
started wiping it on before I noticed (Big words on the front "WOOD OIL;
FOOD SAFE"; tiny letters on the back "mineral oil").

I hate the stuff. It shows fingerprints, and the least bit of water
makes it very dull. Further, there's a very fine "fuzz" on the wood that
I know a drying oil wouldn't have produced.

So the question is, can I now put a food-grade drying oil finish (like
walnut oil) on the block, or am I stuck with it the way it is? There is
absolutely no possibility of getting the mineral oil off; it's soaked in.

thanks, Isaac
