One of those fumes is phosgene (nerve gas) which is why I never use brake cleaner on any part I'm about to weld. An aluminum-only stainless brush is one of the better things to have.
I can TIG aluminum with nary a problem. As has been stated before, practice, keep the work CLEAN, and preheat if possible.
