siliconing technique...

[John Benton]

I always tell my customers once they have showered to take the shower head and spray down the walls to wash off any body fats/oils shampoo residue as this is full of bacteria. Leave it, and mould will grow, clean it down and you will have less chance of mould occurring!!!!

I do the same.

I always tell customers with teenagers, to blame them. 🙂

Ventilation, or lack of it causes discolouration in silicon/grout. If people open a window or had a decent extractor, that would help no end.
