I know they use Muriatic Acid (Hydrochloric Acid) to etch/clean concrete/rocks, etc and it works very well - be careful though as it is very corrosive! Also always remember to add acid to water NEVER ADD WATER TO ACID. Acid is hydroscopic meaning it really really really likes water - it likes it so much if you try to pour water into acid it will try to climb up the stream of water and in the process splash acid everywhere. So when you dilute acid always add the acid to the water and never the other way around.
