Degreasing brakes

[jansens]

I am always wary of brake cleaner. The chlorinated stuff is very nasty and very dangerous if you use it to clean metals then weld them. The heat and argon gas makes it break down into phosgene gas apparently.

The only way to tell is to see if it says non-chlorinated on the can or check the MSDS. This is an example for a locally available one: http://jr.chemwatch.net/CWWS/MaterialSer...nlyfirst=1

I usually prefer acetone for cleaning things.
