I thought I saw somewhere in a build thread that somebody did a quick shot of brake cleaner cleanup before welding (maybe it wasn't here, but if not, still relevant)

You just never know how quickly things can go bad - very bad.

Probably an old article. Tetrachloroethylene was removed from over the counter brake cleaners several years ago. Still, its best left alone.

Wynns MSDS still lists tetrachloroethylene as first ingredient
