Jerry,

I wasn't suggesting using acetone to clean printers! I don't even 
think chem lab students should be using it! It's bad stuff!!! Back in 
the seventies we used it in our chem labs (I think). Rinsing with 
water cleaned out the beakers, alcohol was then used I think to make 
accetone and water get along together, then finally acetone to 
evaporate the last drops out of beaker- no lingering spots. Or so I 
think that's how it went, it could have been the reverse order.

Acetone will craze many plastics, and is highly reactive. IOW, don't 
set a match to it. And is not good to take a bath in either<g>. It 
evaporates so fast it can hurt your skin.

I merely mentioned it as an aside comment, the stuff we did 25 years 
ago to clean lab equipment, etc.
