I am going to paint some exterior brick on my house, ive cleaned the
white efflorence area 3 times with full strength Muriatic acid, I wet
it, let it sit a few minutes, scrub then wash and the next day its
grown back severly, maybe 1/16". There are no visable leaks on the
inside of that wall section. I thought to have effloresence you had to
have an active leak or wet brick, is this my problem that I do in fact
have moisture still pushing out, or is there another cause and a
better way to clean it.
