I buy acetone in gallon cans at Lowes to clean inkjet heads. I've also been able to buy 99.5% pure isopropyl alcohol in liter bottles at Fry's. Some ink residues dissolve better in alcohol. What I miss is 1,1,1 trichloroethane. I worked in food processing plants, specifically margarine and vegetable oil production in the 70's through 1998. We used 1,1,1 tec to clean machinery from 1972 to 1979. Best degreaser ever, but it was nasty stuff. It dissolved almost everything except glass and the special polymer liners on the drums. If you dipped your hand in it, all of the skin oil would be removed and your skin would dry and crack almost immediately. All of this was pre-MSDS of course. The company used to let us take buckets of it home to degrease car parts. James Charles wrote: -- http://webpages.charter.net/jrice54/classiccomp2.html
