here is a copy of a letter which I sent to my son and his wife a few weeks ago.
Dettol Mould and Mildew remover. It is fantastic. Spray on any black mould, leave it for about 20 mins and rinse off. Fabulous, worth every penny.
This is brilliant stuff - Dettol Mould & Mildew Trigger Spray , just spray on and leave for a while then rinse off
Try HG Bathroom Mould spray.
It's pretty vicious stuff, so use a face mask and open the window. If the mould is really bad you might have to do a second application.
I used it in the shower cubical and it really made a massive difference.
These are genuine comments from real people - not sales patter from reps. Let me know how you get on. The Dettol spray is the more popular of the two.
