I have a 1929 roadster with a tan cloth top that needs cleaning. A vinyl cover was put on it for approx. two months and left streaks where the cover touched the top. What should and should not be used to remove the markings?
You might want to check out the "Vinyl Awning Cleaner" that is used on Motor Homes. At least check out their label and find out if it meets the material on your top. I also use it on my white convertible top and if you go by the directions and don't rush the job, it is great on those awful streaks.
Yes, check with LeBaron-Bonney, we have been working on an article for the Model A TImes on this very subject, but they sell a product that is recommended by the company that manufactures the fabric they use for the tops.
