I have a dark red brick house. On the back side of my house I seem to have an issue with efflorescence on the brick. So I did some research and someone mentioned using muratic acid or some form of muratic acid diluted in water. Brush it on there and rinse it throughly.
I did just that and it was gone for a good month. I thought it did it! Within the next month it started to reappear so I did the same thing, scrubbed it with this "Green Envy" cleaner and then rinsed it with water, again it was clean and beautiful for a good month. Winter came and now spring is approaching and finally the snow has melted in Michigan. I look again at my brick and the efflorescence is there again!
How do I get rid of this stuff? I have also tried white vinegar, and that didnt do anything!
Edit It seems that ever since I got my patio deck out back this has happened. Its a pretty high patio with pavers, they had to put a lot of water on the crushed concrete and they then put the pave base and finally the pavers. About 3 months later the efflorescence seemed to appear on the wall in front of the patio. So could this be the issue? What could be causing this and how to get rid of it?
Also I already did search this forum, and I've read the one post but that did not work for me. I was hoping to get better / more answers. (See comments section).
