Removing Convertible Top Stains

Sooner or later, your top will be inflicted with a stain that will not come out with regular shampoo. Common stains include bird droppings, tree sap and grease. For these occasions, you will need to use a stronger cleaner that can penetrate and release the foreign matter.

Your first inclination will be to scrub the stain with the regular shampoo. DON'T! All scrubbing will do is spread it around. To remove stains from your canvas or vinyl top, use Wolfstein's RaggTopp Cleaner in full concentration. Spray it liberally on the stain before washing the whole top. Let it soak in, but don't let it dry. After it has soaked for 3 to 5 minutes, rinse your top and wash as usual. Rinse the stained area with a stiff stream of water.


As I mentioned earlier, canvas tops are not waterproof. To make a canvas top waterproof and stain resistant, it is necessary to treat it with a protective spray. The only treatment I recommend is Wolfstein's RaggTopp Protectant. This is the only product endorsed by Haartz, and the only fabric protectant that contains an antifungus agent to prevent mold and mildew. I have previously recommended Porsche Tequipment Convertible Top Conditioner and 303 High Tech Fabric Guard, however, these products do not offer the same level of protection as RaggTopp and they are not recommended by the manufacturer of the fabric top material.

Although vinyl doesn't need waterproofing, vinyl tops do need protection. Using a good vinyl top protectant, you can prevent discoloration damage from road grime, pollution, salt deposits, leaf gum and bird droppings. The two products I recommend for vinyl top protection are Raggtopp Vinyl Protectant and 303 Aerospace Protectant. Both offer excellent UV protection. Vinyl tops should be treated monthly.

Before you spray your soft top with protectant, it must be clean and dry. Use a scrub brush and a full .75-ounce dose of top or car shampoo to deep-clean the top. Applying the canvas top protectant is best done in conjunction with waxing. Your pre-wax cleaner or polish will remove any potential overspray.
