Uhh so any advice on melting down bars? We have a dozen or so bars from our business that were just in a tub in the shop and got dirty from stuff landing on them. I wanted to wash them off and then melt down and add some essential oil and pour them in some molds for the kids bathroom. Kids love to run through soap. I should be able to just grate it all up and stick in a crockpot with a little water, right?
