Bloody best cleaner ever. Although some liked Genklene,
now also banned.
There are some commercial spray cleaners that claim to be
almost as good. I would like something in bulk for dipping
computer boards. Isopropyl alchohol is suggested by some,
but has 9% water usually.

Not sure where you are, but isopropyl alcohol is usually available
99.9% pure, with a negligible water content.

I'd go along with that. The stuff specified as 'electronics grade' is
typically at least 99.7% to get that rating

the IPA commonly available at drug stores is usually 90-91%,I believe,at
least in the US.

Probably the same here, which is why you have to go to an electronic parts
supplier to get the electronics grade one
