Removing white stains on exterior wall of house
Anonymous user 03/03/2024 - 3.11 PM
I am trying to remove what appears to be discolouring caused by water leaking from a damaged down pipe that has left white marks on the outside brick wall under the bathroom. So far I've tried Ever Build 401 high strength brick & patio cleaner using a scubbing brush but with only limited success. I understand soap and detergents may only make the problem worse and leave more permanent staining. Any tips welcome please.
Are you a tradesperson and able to answer this question?

Hi Avery,
Try Harpic Black, lay it on with a brush (it's quite thick like bleach, wear rubber gloves and glasses/goggles) leave it to soak in for an hour, rinse and repeat. I would be surprised it it won't shift it.
Regards
Simon
