    The following steps are highly recommended:

    • Wash your soft top at least once a month, or when it is dusty or dirty, with a non-detergent-based auto shampoo. If your top is not dirty, rinse it thoroughly with plenty of cool water. Make sure the shampoo does not contain gloss-enhancing oils. Otherwise, the top will absorb the oil and be a dust magnet. Use RaggTopp Fabric Convertible Cleaner Kit.
    • The recommended tool for washing is a soft scrub brush. Do not use a cloth, chenille-covered sponge or lambs wool mitt because they will leave lint. If your top has soil marks, stains or bird droppings then use a small and stiff upholstery scrub brush.
