I had some rats in the back yard under the woodpile. I made a funnel with a 6 foot hose on it and put it down the rat hole. I poured ammonia down it and some bleach right after it(wearing the proper respirator) the white smoke seeped up through the ground.
Shot the rats with .22s and pellet guns on their way out, there was 4 of them. Some were not in good shape by the time they reached the top,looked woozy.
I know this numskull who worked at a butcher shop and there were hundreds of rats under the store down this chute. He thought he was going to gas them and beat them with sticks when they came up. He poured bleach in one hand, ammonia in the other, wearing no mask and he was overcome by the fumes and dropped. The gallon jugs were on the ground with him spilling on him and his clothes.
Then the hundreds of rats came out running right over the top of him like in some horror movie, some tried to get in his clothes. The other guys with sticks got a few of them but the plan did not work out so well. I was laughing my ass of when he told me but he did not think it was so funny.

I stopped using carb cleaner 15+ years ago. Brake cleaner never leaves a residue and dries/evaporates quickly...unlike carb cleaner. The non-chlorinated I've noticed does not smell as strong, but seems to work just as well. Never had a problem, but I've never tried applying heat (and argon) to an area I've used the stuff on. This story is indicative of what happens when a product is misued. So no welding on stuff that has been cleaned with brake cleaner is the lesson.

Or atleast let it dry plenty and blow off the area with compressed air to rid of any residual.
