I have a bit of a messy re-pointing thing happening and a lot of my bricks now look a bit discoloured due to waste cement splashing them. Wire brush has not removed all traces, so I want to know if there is a good chemical I can wash the bricks with?
Any advice appreciated.
Thanks
Rick

Thanks Andy, I'll have a look.

Obviously be careful. It is somewhat concentrated hydrochloric acid and will dissolve certain types of stone etc.
Have a bucket of water on hand and wear appropriate protection. The acid will tend to attack cotton clothing as well.
