Yup, same :-) Still have heaps as well, and don't forget carbon tetrachloride - we'd wash our hands in it at high school !! Yup still alive :-) ahhhh memories

Don't forget methyl ethyl ketone.  That was the solvent of choice for a few years.

Great for dissolving plastics, pure Butanone not sure if I'd want to clean PCBs with that.

Acetone is very powerful.  But young women use it a lot to remove nail polish.

I use a toothbrush and denatured alcohol for the first cleaning stage. I follow up with IPA and a different toothbrush. I then rinse under running cold tap water for about 30 seconds. I have high water pressure here, about 95 PSI. Then immediately dry the board with a hair brush dryer set to high temperature and high blow speed. The boards always end up looking very clean. No signs of damage to the silk screen or solder mask.
