How to Maintain a Convertible Top

1.
Convertible tops should be cleaned at least twice a year, more frequently if a car is parked outside. Use only high quality convertible top cleaners designed for this purpose. If possible, use a cleaner that's biodegradable. Do not use abrasive detergents or scouring powders that contain chlorine-based bleaching agents. They can weaken a top's seam threads and remove essential oils in vinyl tops that are needed for protection against the sun's UV rays.
2. Wash the top in the shade and not in direct sunlight. Make sure the top is cool before wetting. After wetting the top thoroughly, spray a light coating of top cleaner evenly across the top and gently work the cleaner using a soft sponge or brush to scrub away dirt. Once cleaned, rinse off the cleaner while brushing and using lots of water from a nozzleless hose. Continue until sudsing stops and the rinse water runs clear.
3. Do not use ordinary glass cleaners if the window is plastic, since these are too harsh and may damage the plastic. Use cleaners and polishes specifically designed for plastic windows. Try to find one that doesn't contain solvents that can harm the environment. These products will remove minor scratches as well as dirt and help prevent the plastic from discoloring.
4. You don't need to use a top cleaner every time you wash the car. You can usually keep a top clean by washing with plain water. If it's dirty, use a gentle, pH neutral car wash and make sure to rinse thoroughly. After washing, let the top dry completely before folding it down, since this will prevent mold and mildew.
5. After cleaning, use a top protectant to preserve the color and texture of the top material. This will also prevent fading and cracking, and additionally help repel dirt, grease and oil.
6. Remove bird droppings immediately. They are very acidic and can quickly damage tops.
7. Don't let snow accumulate on your top. While a softtop can handle moderate amounts of snow, heavy or wet snow can overload the top structure and bend the metal frame. Be careful when removing snow and ice from plastic rear windows so you avoid scratching the plastic.
