What is it that makes this so toxic? Is it the vinegar/peroxide or the residue from the baffle or the combination of the two?
combination of the two. It creates lead acetate. You'd never want to touch that mess, dump it down the toilet or sink, or in the backwoods somewhere. All of them are not only irresponsible, it's toxic to yourself and the environment. Think of it like dumping battery acid down your drain or into the woods.
