I use a local brand, Steren, 60/40
Yeah I guess it's not no clean, just regular leaded. I just never felt like
enough flux got on the boards to warrant cleaning. I probably should
though, if it's corrosive in the long run. I've only been doing this for 7
years, maybe I'll find out in 20 that I should have been cleaning all along!
What should I use to clean then?
