Friendly advice: do not mix complex compound chemicals at random. Interesting things can happen.

Addendum: The blindness was temporary, before you ask, and mostly due to his eyes swelling shut.
I fondly remember cleaning latrine showers with my gas mask, protective gloves, and undiluted HCL-based cleaner. It works wonders as long as you don't let it sit too long on the tile and have a good seal on your mask.
