[sdiy] Flux residue removal

[Roman]

I never had a problem buying IPA, no special documents required. I think the volume I use is way below REACH directive anyway. So one time I think I purchased 2 tanks 20 liters each. But now I prefer 5l bottles, easier to operate. And I don't use IPA so much now, only for initial cleaning. I do it all now in Electrolube SWAS, which is very good. It takes a lot of contamination without affecting performance. I had to replace IPA in my washer rather frequently, but with SWAS I'm not sure if it's not a whole year already. And it smells good, I can work in it without gloves, and has beatifull color. Boards come out super clean out of ultrasonic washer. Then it has to be rinsed in water.

   substance
   (by provincial law, you have to ask for it at the pharmacy counter
   instead
   of it being stocked on the regular shelf) because of concern alcoholics

   some
   transportation-related issues; my last purchase of a gallon jug arrived
   with an impressive pile of "hazardous goods transportation" documents,
   apparently because of fire hazard.
