I’m on lunch break from this house, and going back to do the driveway in a little bit. There are areas on the brick with small white spots… anyone know what this is, and what could clean it?
In my arsenal, i currently have purple power, F9 BARC, F9 Calcium and Efflorescence remover, and oxalic acid.
Is this calcium or efflorescence?
These pictures are after the housewash:
