Thanks for the reply. Unfortunately the sealant around the bath continues up the wall in corners and then around the ceiling in half the bathroom. A lot of sealant to replace for one mould stain...
Hi,
I've got a mold spot on the silicone sealant around my bath tub that won't go away when I try to clean it. Can I replace only a part of the sealant around the bath (the rest looks fine), or will water start to leak between the old and new sealant?
