How to Maintain Your Convertible Soft Top Roof
Posted by Christopher Nagy on Mar 20th 2025
Keep your classic convertible looking sharp and road-ready with these soft top care tips.
After starting the year with a harsh winter, the arrival of longer daylight hours and warmer spring temperatures marks the return of prime driving season. This shift in weather coaxes some of the most beautiful classic convertibles out of hibernation—whether it's a 1959 Cadillac Eldorado, a 1960s Pontiac GTO, a British MG MGB, or the ever-popular Mazda MX-5 Miata.
These beloved roadsters offer that irresistible wind-in-your-hair feeling. But before hitting the open road, it’s essential to give your convertible soft top the care it needs to keep it looking and functioning its best.
Avoid Storing the Convertible Soft Top Down
While an open-top convertible is a sight to behold, it's not ideal for long-term storage. Leaving the top down can cause material creasing, shrinkage, and even discoloration. Always store your convertible with the top up to protect its structure and maintain its shape.
Clean Your Top with the Right Car Care Products
Due to the delicate nature of a retractable soft top, it’s best to avoid automatic car washes or pressure washers. These can damage the seals, weatherstripping, or even cause tearing.
Here’s how to safely clean your convertible soft top:
- Use a vacuum cleaner with a brush attachment or a lint remover for light cleaning.
- For deep cleaning, choose a fabric- or vinyl-specific shampoo, depending on your roof material.
- Use a soft bristle brush—horsehair or Nylex brushes are great options.
- Apply a convertible protectant monthly to repel water, dirt, and stains.
Caring for the Rear Window
Whether your convertible has a rear window made of vinyl/plastic or glass, be sure to treat it accordingly:
- Use plastic-safe cleaners and microfiber cloths for vinyl windows.
- Use non-ammonia glass cleaners for glass windows.
Always avoid letting cleaning solutions drip onto the soft top material.
Lubricate the Convertible Frame and Weather Seals
The convertible roof frame relies on a system of joints and hinges to operate smoothly. Apply white lithium grease using a brush or swab to these components to ensure consistent operation.
Additionally, your weather seals require occasional conditioning to prevent drying or cracking. Apply a rubber conditioner or seal lubricant every few months for best results.
Inspect Regularly for Tears or Leaks
Unlike metal roofs, soft tops are more vulnerable to environmental damage. Periodically inspect your convertible top for signs of wear:
- Use patch kits for small tears or fabric glue if you're handy with repairs.
- Replace weather stripping or seals if they become brittle or begin leaking.
- If damage is extensive, a full top replacement may be necessary.
UV rays, age, and movement will eventually wear down your roof’s waterproofing—stay ahead with preventative care.
