Hi, I've noticed green mould growing along the bottom seal of the sliding door windows. Decided to give them a clean and noticed that rather than sealing the plastic trim forms a trough at the bottom edge. Its full of mud and general detritus. I'm thinking of a thorough clean and a bit of silicon sealant. Does anyone know how to remove the seals or I am I best just leaving it in place? Thanks

There are a couple of half mooin cutouts in the lower edge of the seals no doubt for water to exit from, so have cleaned out all the crap and job done.
The world will sleep easier now.
