MEK is superior to acetone because it evaporates slower. This gives more time for the solvent to soak into the wood before evaporation begins to reverse the flow. A heat lamp defeats that purpose. The whiting procedure is slow, but it will completely de-oil a stock if you have the patience. When the whiting remains white after drying completely you can be assured that the stock is clean deep down. You can buy MEK at any paint store and many hardware stores.
