How To Clean And Waterproof Your VW Beetle Convertible Soft Top

How To Clean And Waterproof Your VW Beetle Convertible Soft Top

This step-by-step guide demonstrates how to restore your convertible roof using the ProtexWorld Soft Top Cleaner and Waterproofing Kit. While we are using a VW Beetle for this demonstration, the process and products are applicable to any fabric, mohair, or canvas soft top.

The Restoration Kit

A professional result requires the right tools. The ProtexWorld kit includes:

  • Specialized Formulas: Protex Soft Top Cleaner and Waterproofing Solution.

  • Application Tools: A dedicated cleaning brush, two applicator brushes, a drying towel, and high-quality microfiber cloths.

Assessing the Condition

The Beetle in this guide has spent 15 years parked outdoors. Initial inspection revealed a roof that was dry, dusty, and heavily contaminated with green mildew, bird droppings, and lichen stains.

Pro Tip: For a roof in this condition, set aside at least two hours for the full process. If you do not have a garage, choose a warm, sunny day for optimal drying.

Phase 1: Deep Cleaning

Preparation is the most important step in restoration.

  1. Dry Brush: Use the cleaning brush to remove loose surface dirt, paying close attention to the seams where mold often hides.

  2. Dampen: Lightly mist the roof with a spray bottle or a fine hose setting.

  3. Apply Cleaner: Using an applicator brush, apply the cleaner to one half of the roof and let it soak for five minutes.

  4. Agitate: Gently scrub the fabric using hot tap water and the cleaning brush.

  5. Rinse & Dry: Thoroughly rinse until all foam is gone. Use the provided drying towel to soak up excess moisture and allow the roof to air dry for approximately one hour.

Important Safety Warnings:

  • Avoid Harsh Chemicals: Never use bleach or solvent-based products.

  • No Pressure Washers: NEVER use a jet washer on a soft top; the high pressure can cause irreversible damage to the fibers and stitching.

  • Repeat if Necessary: For stubborn mildew, repeat the cleaning cycle until the fabric is pristine.

Phase 2: Waterproofing & Protection

Once the roof is completely clean and dry, it is time to seal it against the elements.

  • Application: Apply the waterproofer with a clean brush, starting from the center and working outwards until the entire top is covered in one session.

  • Clean as You Go: If any solution splashes onto the glass or paintwork, wipe it away immediately with a clean microfiber cloth.

  • The Result: After curing, rain will "bead" on the surface, preventing water and dirt from soaking into the canvas fibers.

Maintenance Schedule

To keep your convertible looking like new, we recommend following this schedule:

  • Vehicles Parked Outside: Waterproof every 6 months.

  • Vehicles Garaged: Waterproof every 12 months.
