Hydrogen hydoxide!
OMG, it’ll erode anything.
It kills people as well. Every year over 9,000 people are killed by hydrogen hydoxide in the US alone. Many of these people are killed in their own back yards or on vacation.
Hydrogen hydoxide is also highly physically addictive.
Studies have shown that any mammal that consumes hydrogen hydoxide cannot cease consuming it (or products that contain it) without dying.
Mammals that go through hydrogen hydoxide withdrawl die a terrible death, lips cracking and blood actually thickening in the veins.
