Hydrofluoric Acid

Back in college, I did research in a chem lab. Some of our experiments essentially created glass. This glass would end up being bound to the glass test tubes in which we ran our experiments. Cleaning glass out of glass is extremely difficult. The worst cases required using Hydrofluoric Acid.

I hated doing that. I was always creeped out for days afterwards.

I'd describe what it would do to you if you spilled any on you, but Joshua does it much better than I can:

Well, let me see. It's highly corrosive. In its pure form, like we have it here, it volatizes at room temperature. As a vapor, it explodes on contact with metal. In liquid form it can soak in wood, concrete, cloth or plastic and make the surface it's soaked into corrosive to human flesh for years afterward. And it passes through your skin and binds up with the calcium in your bones. So basically, you get this stuff on you, your bones turn to jelly, your skin starts coming off in sloughs, your nervous system shuts down and you die. Then your body's categorized as toxic waste and disposed of by being encased in molten glass.
