On top of that, I think my canister of Lysol wet wipes and many other bottles of cleaning chemicals says something like "it is against federal law to use this product for any purposes other than its intended use"

Like, yeah it's illegal to do illegal stuff with or without the label, but at least Lysol could say "we did tell him that he can't use it for that."

It's illegal to do illegal stuff, but it's not illegal to do off-label usage stuff. If I want to take your hydrogen peroxide you sell as a surface disinfectant and mix it with vinegar and salt to etch my PCBs at home, that's my prerogative.

Well, who's gonna tell on you? :) I don't have a bottle of H2O2 handy so I don't know if it normally has that disclaimer.
