Took me 5 years to realize I was cleaning flux wrong with isopropyl alcohol.
I used to just dab at solder joints with a q-tip and 91% alcohol, leaving that white sticky film everywhere. Then a guy at a repair meetup in Portland told me to switch to 99% and use a stiff brush instead of dabbing. Anybody else find out the hard way that lower percentage alcohol just makes things worse on boards?

91% is basically useless, it leaves behind too much water and flux residue. 99% and a stiff brush is the only way to go for clean boards. Learned that one the hard way too after years of sticky messes.

Man, I've been there. In my experience a quick dry brush after 91% makes a huge difference.
