Removing mould

Yep, the mould is obviously underneath. Looks like I'll need to cut the silicone out and replace. I drenched rolled up toilet paper with loads of bleach, left it overnight but none of it disappeared.

Hey guys, I just found this unopened tube of clear silicone but I don't know the age of it. It's either 5 years old or 1 year old as I had two lots of work done in 2012 and 2016. I can't see any expiry date. There's some vaguely visible numbers on the side in the second picture if anyone can make sense of them? Do you think I can use it?

This would have been for the basin and around my shower screen as they have clear silicone. I'd still buy the no nonsense white silicone for the bath area.

If it’s gone hard in the tube then it has expired.

Good point. Also, I think that if it does still squeeze out, I'll have see if it sets and forms a skin. I'll try it on a test area first.

Wow, that's not very good. Less than a year.
Where is the date on your tube? Can't find one on mine unless it's that vague number on my photo above.

As long as it hasn't gone hard and you're not doing the whole house in the stuff I'd just chance it. I've used sealant months after I've opened it before even though you're not meant to*

* I did seal the nozzle by sticking a screwdriver down it into the tube and then taped it all up to make it air tight

For the bits near the bath, roll up toilet paper into tubes, lay it against the silicone then douse in bleach, leave for 48 hours and it should remove it.

I did something similar last year after watching a YouTube video on it with lots of positive comments, worked pretty well and certainly a lot easier / more effective than just applying bleach and elbow grease.
