It's not uncommon to see the rear window of a convertible top look cloudy, hazy or even worse, yellow. Sometimes it gets so bad, that the window eventually becomes brittle and breaks.

For many years now, plastic windows have been made from a 40 mil PVC plastic because they are affordable and effective. However, they are prone to aging and browning and if neglected, can become a safety hazard. The plasticizers in the plastic leach out over time allowing the plastic to become brittle and hard over time. A plastic window that's allowed to do this will become hazy and eventually become opaque making it impossible to see through.

Fortunately, it's not as hard as you might think to keep the window clear and in great shape. We'll show you two ways to keep those windows crystal clear.

Solution 1 will show you how to deep clean your convertible window if it has lost some of its clarity due to the accumulation of hard water spots, mineral build-up and road grime.

Solution 2 will show you how to remove fine scratches and haze from the window restoring them to a like-new condition.

Just remember while both of these solutions are very effective, they do not perform miracles. If your window is yellow, cracking or severely cloudy, you might have no other choice other than to replace it.

 

Solution 1 : Deep Cleaning

Weeks, months or years of sun, hard water, road grime, air pollution, ocean air salt, sap and other environmental pollution can take a toll on your convertible window. The plastic material makes the window light which benefits your car's overall weight balance but the plastic lacks durability to deal with everyday driving. It's important to maintain with regular cleaning to keep it in optimum condition and maintain clarity. If you've neglected it for a while, follow this deep cleaning treatment to restore clarity.

After cleaning

Step 1

Window should be clean prior to treating. Remove any dust and debris with a damp cotton terry towel.

Step 2

Working in the shade and making sure the window is cool to the touch, spray Plastic Deep Cleaner on to the surface and allow to penetrate for a few minutes then agitate with a 100% cotton terry towel. Rinse the towel in clean water as needed to remove dirt. Repeat until window becomes clear.

Step 3

Finish by cleaning the surface with nextzett Windscreen Clear and a microfiber towel. Microfiber towels are softer than a cotton terry towel when deep cleaning isn't required. It's also lint-free. Microfiber towels last for hundreds of washes and are a must-have in your cleaning accessory arsenal.

You are now complete!



Solution 2 : Haze and Scratch Removal

If the window is cloudy due to scratches and oxidation (haze), you'll need to polish the surface. This can be done using No. 2 One Step Polish. You might ask why we would suggest using a paint surface polish on your convertible window. It's simple. Your car's paint finish is essentially plastic. The abrasives in One Step Polish "see" your convertible window and paint finish as the same type of surface. The abrasives in the polish are just the right size and density to effectively polish the haze from your convertible window. Here's how to do it.
