I've just made my first traditional salad bowl (of cherry wood) that I will give away to be used for food. I finished it with a few coats of mineral oil/beeswax mix, but after reading a lot more about finishes for utility bowls, I think I'd rather use Mahoney's Walnut Oil or maybe tung oil cut with citrus solvent (maybe Corey's). Is it too late, or can I remove the mineral oil by washing with soap and water or another method?
