I just recently purchased a 2013 E350 convertible. It looks like someone along the way might have used a power washer on the top! Go figure. Anyway I was wondering if anyone has had any experience with using a convertible top dye? I was thinking that perhaps this would help revitalize the tops appearance.

 

Tons of these videos exist on YouTube; search on Google or YouTube "Revitalize Soft Top" or "Restore Soft Top", or something to that degree. You should find what you're looking for.

 

If the fabric is black, you can use Solution Finish. It brings everything it touches back to a factory new finish, especially plastic trim. Also works on fabric, but you'll need to try it on something similar to make sure your using the right applicator to avoid streaking, I use it mainly in engine compartments, interior and exterior trim, and tires, but it works on fabrics as well.
