I think they are very useful for awful condensation in my bathroom BUT I left it unemptied when I went on holiday and now there seems to be a residue of black in the tank- presumably what makes the grouting grubby if I leave the walls dripping. It has no way that I can think of to get it clean. Any ideas please.
Why do people lie online are they living a fantasy or winding us up?
