Monkey, I think the heat has to vaporize the chlorinates. His MIG welding did that job. Still, non-chlorinated cleaner is the way to go.

The consensus on cleaning cats off the car is that you can't. People have tried running toluene, acetone or lacquer thinner (which is mainly toluene and acetone) in the gas tank as high as 10%. I think if that works, it's because it cleaned up some other parts along the way, like injectors. I've heard that it produces higher than normal (which is high enough) temps in the cat accelerating carbon burn off.
