For green mould or alge Tooth brush and diluted bleach then rinse off with clean water. If it's just dirty sealant try cleaning wipes or tcut on a wet cloth

Amazon product ASIN B004QXGGBEBrush on or use a sponge, apply on a dry day, and when liable to stay dry for at least 4 hours. Allow it to sit on the joints till yu next clean the van, or sooner if your keen to see the result.Reapply when the mould/algae comes back. For coach built's it also works on the hab to cab joint line over the windscreen.
Caveat, test a small inconspicuous area first .
