I've got a parts washer that I haven't used in several years (10+?) I remember the drain plug was leaking, and I stopped using it for a while. Moved, it was in the stuff that wasn't being used, and now, I need it to clean some parts for the race car. It's an old harbor freight unit, what should I do before starting it up after all this time? Also, is there a sealant or something I should use on the drain plug to keep it from leaking? Thanks!
