I also read a piece on the same basic thing.Don't light it on fire either....
Another good read.
About 12? years ago had one of my coworkers drive a forklift fork thru the alum front rail of my Featherlight car trailer. Made a 4" gash in the rail, easily tig welded. So after brake cleaner cleaning and SS wire brushing, and waiting hours completely outside in the Florida sun, wearing a full welding helmet, I Tig welded up the damage. Maybe a 1/2hr? tops welding time. What could go wrong?I also read a piece on the same basic thing.
It was about cleaning metal with brake clean before a weld. The fumes can cause some bad symptoms.
