Repeat the process until the stain is gone. Sometimes this takes 4 or 5 cycles.

And the wire brush takes a few seconds and leaves no residue or white marks. When you pour Muriatic acid on the stain it tends to run making an even larger mark on the porous pavers and to avoid acid stain you have to time the rinsing perfectly, too long you end up with white spots, not long enough the iron stain remains. Pavers are not the same as a concrete drive. The wire wheel is so simple, easy, and fast why not try it.
