I bought a fairly nice air compressor at a garage sale. It works pretty good after I fixed some things on it. However I have one big problem. The previous owner used it for painting (he was a painter). Now when ever I use it, the paint fumes come out of the hose. After an hour or two my head hurts. Draining the tank will just about knock you out. Is there any way to clean this tank? Who would do it? I'm almost to the point of selling it because I can't use it which really would blow. Thanks for any help.
