Brick acid, can you get it here?

[a1sysman]

Good afternoon all

I need to clean natural stone paving of excess render, mortar, cement stains, and other man created blemishes. Jet washing is laboriously slow progress. I have used brick acid in the UK to clean similar stone work. Is it possible to purchase brick acid, or similar, over here. If so, where from please?

TIA

I suggest you got to the yapi market for ceramic tile cleaner but it's not that strong. Otherwise acid for pool tile cleaning is stronger.

Thanks for the suggestions. I am carefully trying pool tile cleaner, tuz something-or-other. A lot of bubbling and frothing but not the muck shifter I hoped for, at least not so far.

Tuz Ruhu on recommendation of a friend, has brought out the dirt on our patio tiles (now the flooring in conservatory) - it does froth and brings the dirt up for washing off. Better than anything else I have tried but not perfect. Will take a lot of bottles as spreading it neat, not diluting it. Be careful as toxic acid type.

Tuz Ruhu is 20% by vol. Hydrochloric acid.

Count your fingers after using it!

Also be careful re breathing in. Stuff is lethal and that's were a decent mask comes in. It actually "melted" a scrubbing brush I was using.

Thanks one and all. I will continue, carefully, with tuz ruhu for the time being. Would like something a little stronger and will keep looking.
