Convertible Top & Soft Top Care: Clean, Protect, and Extend the Life of Your Roof

A convertible top is one of the most exposed and vulnerable surfaces on your vehicle. Constant UV exposure, rain, bird droppings, tree sap, and mold all take a toll on soft top fabric. Without regular care, a convertible roof can fade, shrink, develop mold, and lose its waterproofing — leading to expensive repairs or replacement.

Types of Convertible Tops

• Fabric/canvas tops — Most common; require fabric-specific cleaners and waterproofing treatments
• Vinyl tops — More durable but prone to cracking; use vinyl-safe cleaners and conditioners
• Hardtop convertibles — Treated like regular car paint; standard wash and wax applies

What You'll Need

• Soft top-specific cleaner (fabric or vinyl formula)
• Soft bristle brush (never stiff or wire)
• Microfiber towels
• Fabric waterproofing/protectant spray
• Garden hose (low pressure)
• Mold and mildew remover (if needed)

Step-by-Step Soft Top Cleaning

Step 1: Rinse with Low-Pressure Water

Use a garden hose — never a pressure washer — to rinse the top. High pressure can force water through seams and damage the fabric structure. Rinse from front to back to direct water away from seals.

Step 2: Apply Soft Top Cleaner

Spray the dedicated soft top cleaner generously across the entire surface. Allow it to dwell for 2-3 minutes to loosen dirt, bird droppings, and organic matter.

Step 3: Agitate Gently

Use a soft bristle brush in straight strokes — never circular — to work the cleaner into the fabric. Pay extra attention to seams, folds, and areas where mold tends to develop. For vinyl tops, use even lighter pressure to avoid surface abrasion.

Step 4: Rinse Thoroughly

Rinse completely until all cleaner residue is removed. Leftover cleaner can attract dirt and degrade fabric over time.

Step 5: Allow to Dry Completely

This is critical. Never apply protectant to a damp top. Allow the roof to air dry fully — ideally in sunlight for 1-2 hours. Applying protectant to a wet surface traps moisture and promotes mold growth.

Step 6: Apply Waterproofing Protectant

Once fully dry, apply a fabric waterproofing spray in even, overlapping passes. Allow it to cure per the product instructions before exposing the top to rain. This step restores the water-beading properties that keep your interior dry.

Dealing with Mold and Mildew

If you notice black or green spots on your soft top, treat them immediately with a dedicated mold remover before they spread. After treatment, always apply a fresh coat of protectant to prevent recurrence.

Pro Tips

• Clean your soft top every 4-6 weeks
• Reapply waterproofing protectant every 3-4 months
• Never fold a wet or damp top — it promotes mold in the folds
• Use a convertible top cover when parked long-term
