Limescale Deposit - Brick acid not working All manner of questions and solutions to problems and issues surrounding the subject of brickwork, blockwork and stonework

[gregjones]

I have a property where the overflow has been leaking for years. The wall has a large white streak down it. I have tried brick acid in the past but didnt have much luck and it seemed to start damaging the bricks. Any ideas?

Thanks in advance.
