If you are planning on cleaning anything before welding, do yourself a favor and use Isopropanol or Acetone. The tetrachloroethylene in Brake Cleaner and other solvents can turn to HCL or Phosgene gas and can cause severe toxicity, long-term nervous system damage and even death when exposed to extreme heat in the presence of Argon.

While we're on the subject of safety, always sweep up the area around your grind operations when switching between Aluminum and steel. The combination, in the right settings, will make Thermite. If you don't know what Thermite is, all you need to know is that it is used in explosives.
