Very common issue with certain tops i’m afraid!
Judging by the areas in which you say the marks are present, I can surmise that they are “fold marks”, however, if they are white streaks caused by a power washer, then unfortunately, it will be a much greater issue!
However, the fold marks or “scuff marks” that I am sure you refer to, are caused by the fabric of the soft top rubbing against itself whilst using the folding and unfolding mechanism. Some soft tops are more prone to these “scuff” marks than others. You can clean your soft top to help reduce the marks (as dirt within the fibres of the soft top will increase the friction) with the Fabric Soft Top Cleaner and then use Reviver to spruce up the colour.
Although the Reviver will mask the marks over the roof support bars, when you start to fold down the top up and down again the marks will begin to reappear; as these are simply caused by friction of the material rubbing against itself.
You must use the Reviver product on the whole roof, and NOT just the areas that have fold marks, otherwise you will have a very patchy result, which would mostly likely highlight the fold marks even more so!
Renovo Ultra Proofer is a fantastic way to waterproof and protect your top from becoming ingrained with dirt once you have achieved the colour that you desire by using Reviver!
