We bought coutners from IKEA. The person helping to finish the bare wood suggested. I am watching TOH right now, and he suggests some sort of mineral oil. They talked about other finishes that are no good, as they contain toxins, others degrade with food use. The plumber advising the helper suggested boar varnish. He works in kitchens all the time and his work is good, but this sounds wrong to me. Can anyone confirm if boat varnish is the right material to use for a kitchen counter? If not, what would you suggest? If mineral oil, is there any specific kind of mineral oil, or just go into Home Depot and ask for "mineral oil."
