Generally, cleaning a convertible top can be accomplished with car wash soap and a soft scrub brush. If you feel the need for something stronger, consider trying a dedicated convertible top cleaner. Some companies make separate cleaners for cloth and vinyl tops. Meguiar’s convertible top cleaner will work on either material. Spray the product lightly on the top, and wipe it off first with a wet terry cloth towel, then again with a dry terry cloth towel. Wait until the top is fully dry before retracting it.
