I've got green algae on my soft top, and I've read the how to guide which refers to using proprietary cleaning products. I've washed my soft top and used a soft brush a couple of times but it's not moved it ( below is immediately after washing).
I've read elsewhere recommendations to use diluted Milton to kill the algae, anyone else tried this. Also just regular washing with mild detergent. Plan is to treat it with Renovo once the mold has been removed.
