Wel'p, I own a plumbing-supply in PA. I sell a product called "Scrubs in a bucket". Its generally a strong, yet mild (ie; safe) hand cleaner that removes ALL sorts of contaminants. I actually use this product regularly. Upon restoring an older british car (more than one, even) I used these disposeable wipes on EVERYTHING! Cleaned up grease under hood, tar from body, gook off the dash, rubber from paint, <fresh> overspray etc etc. It is safe, nontoxic, smells purtty and biodegradeable!! You should be able to find this stuff in plumbing supplys, janitorial supplys or Grainger co. near you. White bucket, blue lid and writing, Scrubs in a bucket, goood stuff (oh yea, cleans your hand darn good too.) sells around $11.
