Hello all,
Since that icy blast that we had a few weeks ago my garden wall, which is about two years old, has a white powdery patch on the brickwork. I tried giving a good wash with a pressure cleaner but it's too stubborn for that.
Is there a safe way to remove it chemically.
I have quite a few grand-kids plus the neighbours children so I don't want to use anything that would affect their well-being.
Thanks for all help.
