Green Roof Clean | VW Golf Cabriolet Video

Here we have a before-and-after of a Golf with has quite a lot of roof-green. This is algae and moss which has grown on the roof because the hydrophobic coating has worn off and so the roof is allowed to stay wet.

Here we have a before-and-after of a Golf with has quite a lot of roof-green. This is algae and moss which has grown on the roof because the hydrophobic coating has worn off and so the roof is allowed to stay wet.

With the dirt on the roof, plenty of sunshine and water, this creates perfect conditions for growing moss. Once we give it a proper clean and apply our two year weather-proof coating, the car looks almost as good as new, except for some darker wear marks.

These are caused when the roof is folded when it is dirty. Grit that gets into the fabric acts like liquid sandpaper, which is why it is important to keep your roof cleaned and waterproofed.
