How do you properly clean and maintain a convertible?
A convertible is properly cleaned and maintained by treating the paintwork, soft top, seals and interior according to their specific materials, cleaning them regularly and protecting them specifically against UV radiation, moisture and dirt. The key is to care for the soft top separately, use suitable cleaning products and follow gentle procedures. This ensures that function, appearance and material integrity are preserved long term.
A convertible combines different, sometimes sensitive materials, each with its own care requirements. For this reason, it must not be treated like a closed vehicle.
When which solution makes sense
- If the soft top is visibly dirty, clean it specifically with a material-appropriate convertible top cleaner.
- If water no longer beads, reproofing is advisable to repel moisture and dirt.
- If green deposits or moss appear, persistent moisture is usually the cause – thorough cleaning with a soft brush is required.
- If the vehicle is frequently exposed to sun, additional UV protection is necessary for the soft top, paintwork and seals.
- If the convertible is stored for a longer period, clean, dry materials and proper ventilation are essential.
Step-by-step
In this video tutorial, you will learn the correct steps for cleaning and sealing convertible tops.
Preparation
- Park the vehicle in the shade
- Close the soft top completely
- Rinse off loose dirt with clean water
Application
- Treat the soft top with a dedicated cleaner such as Fabric Top Cleaner
- Work with a soft brush or sponge without applying pressure
- Rinse the cleaner thoroughly and leave no residues
- Wash paintwork and glass separately and gently as usual
Aftercare / Protection
- Allow the soft top to dry completely
- Protect textile tops with a reproofing agent such as Lotos Protectant
- Treat vinyl tops with a coordinated care system such as Vinyl Clear Kit
- Condition seals, for example with Seal Feed, to maintain flexibility
Common mistakes & myths
- “A convertible top belongs in the car wash” – brushes and harsh chemicals damage seams and surfaces.
- “An all-purpose cleaner is sufficient” – unsuitable surfactants attack fibres or vinyl. Solvents and alcohols can even dissolve adhesives inside the top and cause major damage.
- “Reproofing is optional” – without protection, water and dirt penetrate faster and remain in the fabric much longer.
- “Seals do not require maintenance” – untreated seals become brittle and lose their sealing function.
Professional tip from practice
Never clean a convertible top more often than necessary, but as often as required. Light soiling can often be removed with water, while a complete cleaning and reproofing can typically be carried out every one to two years. Using less chemistry, but applying it precisely where needed, preserves the material sustainably.

A convertible requires differentiated care because several sensitive materials come together. Those who treat the soft top, seals and paint separately and protect them specifically will preserve not only the appearance but also the functionality for many years.
