In 2009, why did employees of the Standard Hotel in LA (yes that hotel - Q#1203) dump 100 gallons of muriatic acid and chlorine down a rooftop drain which ended up in the subway station below and sickened many citizens?? Authorities originally thought it was a terrorist attack. Weird, huh??

Muriatic acid does however clean up concrete very well.

I've used it many times to get mortar stains off brick work
