I only make the distinction because 'rubbing alcohol' is not always Isopropyl, at least not in the US.

In fact, getting back to melting ABS, skipping down to the Legislation section of that article:

In the United States, ethyl rubbing alcohol, USP and all preparations coming under the classification of Rubbing Alcohols (defined as those containing ethanol) must be manufactured in accordance with the requirements of the US Treasury Department, Bureau of Alcohol, Tobacco, and Firearms, using Formula 23-H (8 parts by volume of acetone, 1.5 parts by volume of methyl isobutyl ketone, and 100 parts by volume of ethyl alcohol).
Acetone will dissolve ABS, so perhaps ethyl rubbing alcohol is what wiggyx has encountered previously. I've made the acetone mistake before and the results are ugly.
