I have tried everything to get rid of the "stains" as most would call it, out of my cloth top on my deville. I have tried woolite, a cleaner which is specifically for cloth top that I bought at a pep boys. I have also used a brush and some soap but they will not budge. Is there anything out there that can get rid of this. It is all over my roof. It is even more noticeable when the cloth is wet. Any help would be greatly appreciated.
