Mould behind the clear sealant - what can I do?

[Kitttty]

remove the lot and start again? how do I prevent it happening again?

In the bathroom? It's just one of those jobs that needs doing every so often. Yes, remove and start again.

yes. I've just done this. make sure you remove it all. then ensure it's completely dry. then reseal using white sealant?

thanks - was delighted when tiler did the sealant in clear -- but now I see the down sides...will revert to white
