Anyone acid wash their concrete?

I did it for a garage where I put an epoxy finish on it. You use muriatic acid. Although you can burn yourself if not careful it's a simple process of broadcasting it over the surface with a PLASTIC watering can, brushing it around and hosing it off. If this is for a basement, I'd set up some temporary ventilation fans and if you can't hose it into a drain then you need to vacuum it up. Flooding it with water before sending it down the drain (I'm sure this'll evoke a barrage of environmental comments) or vacuuming it neutralize the acid.

Google webstites about garage floor epoxy or coatings and you'll find a lot of companies that offer the products. Not sure about any contractors that do it but a knowledgeable painting contractor could do it
