Can anyone recommend a good convertible roof cleaner? I have tried the Turtlewax kit (cleaner and waterproofer) but I still have green mildew marks n the stitching and bird muck marks which I can't seem to shift?
I have cleaned my roof 3 times in total and also tried using a soft bristle scrubbing brush.
Also does anyone know if I can buy roof dye? my roof is black but looking a bit faded after 15 years.
