Renewing silicon sealant in a shower cubicle

[Noreng]

The silicon sealant in my shower is going black with mould and we cannot clean it, so needs to be renewed I guess. I have read a few tips on this and am ready to go apart from one Q.

The vertical corner silicon joints are still perfect, only the joint round the shower tray needs replacing. However can you get a good seal of new silicon to old, or is it best to take it all out and replace the lot at the same time?

Replace the lot.

silicone eater from tradetiler and as sir ramic says replace it all!

[david campbell]

replace the lot as above,a lot easier than it looks with silicone eater

black mould most often comes from the contaminates in human silava,
so after removing all the silicone, clean well with alchol wipes,
wait to dry and apply silicone using a silicone tool......and dont lick your finger and touch the silicone!!!!!!!

best wishes
