We had a shower installed about five years ago. A tiled enclosure and a GRP shower tray. I don't know which silicone mastic the builder used to seal between the tiles and the tray, but it started going mouldy within a year. I cut as much as I could out with a sharp Stanley knife, and then the fragments with a scalpel before attacking the residue with Silicone Eater, an evil-smelling gunk. After cleaning the whole joint with water, meths etc, and drying it with a hair drier, I gunned in some re-assuringly expensive sanitary silicone. It might have been Dow-Corning's, I forget.

Two weeks ago, we noticed that the black spots had returned and seemed to be growing daily. I really didn't want to go through the whole process again so I thrashed around on Google. The general message was " You are doomed, mate....cut it out and start again"......but somebody posted a simpler solution......

All you have to do is squirt some thick Domestos bleach on the joint, and then press some twisted bits of kitchen roll into it. This keeps the bleach from leaking off the mastic. Press the paper into a mush and leave it there for an hour. If it looks a bit dry, squirt some more Domestos on to it.

I was sceptical about it.....it really does work! Not a trace of mould left.

I used to work for a subsidiary of Dow Corning which had the licence to sell their silcone products here. We used to advise soaking cotton wool in bleach and leave it over night on the mould patch. So the same idea basically and yes it does work.

Sand blasting for Rocky's teeth I think.

HG mould spray, designed for the job, less aggressive than bleach. £5 a bottle, lasts forever. Spray, leave a few hours rinse off with shower head, also deals with the grout lines.
