I had unpleasant experience with some consumer chemicals. Removing paint from the balcony barriers, I didn't bother to cover my feet. When a small piece of paint with acid in it landed on my bare foot top, I thought that was nothing special, but it started to feel burning more and more, so I had to go wash it off in the bathtub. After this happened the third time, I finally decided to tie cardboard pieces to my legs and feet. No scars were left, probably thanks to the immediate burning feel.
Another time, I used so-called anti-grease cleaner, which is an alkali just stronger than common soap. Usually it comes as dense liquid like "Fairy", but that one was spray. I wondered why, and I saw it work better than the previous ones, but failed to add 2 + 2. The % of the alkali was higher, it was a lot more aggressive, that's why it was enough in smaller quantities.
Washing a pan inside with a brush (I did put on protective glasses), I felt it stick to my finger, but bother washing it off. When I did, I was already feeling the skin and the flesh underneath burn, and they shrank noteably, exactly like after you touch hot stove inside surfaces, or hot gas oven grill. I feared I'd have to treat it for couple of weeks, but magically that evening the finger came to normality, and no scars were left. Whew!..
An even worse one isvhosuehold rust / lime stain remover; some of it contains hydrofluoric acid which can penetrate some types of gloves, go through your skin, and damage your bones. And you won't feel anything for a few hours. It's unbelievable to me that such a solution can be sold as a household chemical when there are far safer alternatives.
