Do you want to be sure whether Clear Plastic Cleaner & Protector is suitable for your plastic window or transparent screen? Below you can read exactly which materials this product is designed for – and where you should not use it.
Which types of transparent plastic is Clear Plastic Cleaner & Protector suitable for?
Clear Plastic Cleaner & Protector is developed for transparent, smooth plastic used as windows in outdoor applications.
Suitable for:
- Soft PVC
- Vinyl windows
- Flexible transparent plastic sheets
The product cleans gently and leaves a protective layer that helps the surface stay clear for longer.
Can you use Clear Plastic Cleaner & Protector on tent windows?
Yes.
The product is highly suitable for tent windows made of soft, flexible PVC or vinyl. These are the most common transparent windows in camping tents and awnings.
Always use a soft cloth and avoid pressure to reduce the risk of scratching.
Is this product suitable for windows in boat covers and convertible roofs?
Yes.
Clear Plastic Cleaner & Protector is suitable for:

- Convertible soft tops with flexible rear windows
These windows are sensitive to dullness and dirt build-up. Regular cleaning and protection help maintain clarity.
Can you use Clear Plastic Cleaner & Protector on caravan and motorhome windows?
This depends on the type of window.
Many caravan and motorhome windows are made from more rigid plastic such as acrylic. If in doubt, always test first on a small, less visible area.
Do not use abrasive cloths or products.
Is Clear Plastic Cleaner & Protector suitable for acrylic and polycarbonate?
The product can be used on smooth acrylic or polycarbonate, provided the surface does not have a special coating.
Always test first on a small area to ensure compatibility.
Can you use this product on headlights and plastic covers?
The product is not specifically developed for headlights or technical vehicle components.
On transparent plastic covers without special coatings, it may be used carefully. Always test first on a small area.
Is Clear Plastic Cleaner & Protector suitable for helmet visors and windscreens?
Be cautious with helmet visors and windscreens.
If the surface is clear, uncoated plastic, the product may be suitable. However, many visors have special anti-scratch or anti-reflective coatings. In such cases, testing beforehand is essential.
On which materials should you not use Clear Plastic Cleaner & Protector?
Do not use the product on:
- Cotton or canvas fabric
- Synthetic tent fabric
- Painted or coated surfaces
- Matt or specially coated plastics without prior testing
- Glass
For fabric, use dedicated Ultramar cleaners and protectors. For plastic windows, use only products specifically developed for plastic.
Important within the Ultramar maintenance system
Ultramar always works material-specific:
- Cotton and canvas → cleaning, stain removal and protection with dedicated products
- Synthetic fabric → specific cleaner and protector
- Plastic windows → Clear Plastic Cleaner & Protector
Never use fabric waterproofing products on plastic windows. Each material requires its own maintenance approach.
In short
Clear Plastic Cleaner & Protector is suitable for transparent, flexible plastic such as tent windows, boat windows and convertible rear windows. For more rigid plastics or specially coated surfaces, always test first.
By using the correct product for each material, you maintain clarity and help prevent damage.
Ultramar helps consumers clean, maintain and protect boat covers, tents, convertible roofs, plastic windows and other outdoor materials themselves, using PFAS-free maintenance products that are easy to use at home and based on a proven three-step maintenance process.
