Black mould spots on sealant along shower tray

[jalopy]

What gets rid of it. Tried mildew/mould spray and have tried bleach spray. So far - unimpressed. Anything else I could use?

After getting rid treat with a steam cleaner if you have one/can borrow one. Mould is a live organism and the steam will kill it (if the bleach hasn't) so it will take longer to return.

Anyone got tips for the best way to clean granite worktops? Lovely though they are, I'm finding it completely impractical to maintain their high shine.

speccy - agree with your tip - neat bleach on a toothbrush does it

Thanks all. Will try your suggestions.
