How Clean Old Mortar Off Reclaimed Bricks With Muriatic Acid 

this was very cool. I just regrouted my flagstone patio. the job looks perfect except for the thin concrete layer all over from dry concrete sand mix. i will cut the acid with water sprat on and brush in then rinse. should work. thanks

Almost 14k views but no comments hmm. My main thought was if you reset the acid for each brick then it will cost a fortune for thousands of bricks you said you need to remove the mortar from. So I assume that was just to demonstrate to the viewers what to do with the solution after cleanings your bricks for the day?

I'm so curious how it went doing 1,000s of bricks this way. It seems like it would be so slow -- did you have a process that worked well?

very interesting.......I've got 200 bricks that need that treatment, do I need to repeat that whole process 200 times?

That's a long process to "demortar" a lot of bricks. I'd probably just put them all in a large tub, pour the acid over it and let it set for a while to remove as much mortar possible..
