Can someone help me out with the difference between limescale and mildew?
I have horrible brown bits on the plaster between the wall tiles and my shower tray in my en suite. The build-up is underneath the plaster and therefore is impossible to remove without pulling off the plaster and risk water penetration into my downstairs room.
I can't remember how many times I've had to remove the plaster, clean off the limescale / mildew, apply new plaster and wait for it to dry. There must be an easier solution. We live in a hard water area and the en suite has an extractor fan.
