Its Basically mineral spirits, Also hand washing is a very BAD idea as your skin absorbs the solvent and processes it thru your body. Studys I have read show solvent in the urine in 45 minutes after passing thru most of your organs. There are a number of good handcleaners out there be sure and find a good one.
