Many thanks to Stefan for making me examine an incorrect belief I have long
held about Ethanol. I have revised my pages on Ethanol as a cleaner, and
added a page on the formulas used here in the US. It would be interesting
to know the actual formula for the denatured alcohol that Stefan is using.
Clearly the stuff sold as denatured alcohol here in the US is nasty stuff,
and it will definitely attack ABS. True PGA is next to harmless on ABS.
