How to remove old weathered protective film from PVC window?

Reading Time: 3 minutes

Removing old, weathered plastic film from window profiles can be a bit of a challenge, but here’s a step-by-step guide to help you through the process:

Materials you’ll need:
1. Hair dryer or heat gun
2. Plastic scraper or credit card
3. Isopropyl alcohol or glue remover
4. Soft cloth or sponge
5. Warm soapy water
6. Razor blade (optional)
7. Gloves (to protect your hands)

Step-by-step procedure:

1. Softening the adhesive:
Start by gently heating the plastic film with a hair dryer or heat gun. Hold the heat source a few inches from the film and move it back and forth. The heat will help to soften the adhesive under the film, making it easier to remove.

2. Peel off the film:
Once the adhesive has softened, use a plastic scraper or credit card to gently lift one corner of the plastic film. Gradually peel the film away from the window profile, applying even pressure and pulling at a low angle. Try to avoid pulling too hard as this may cause the film to tear or leave residue.

3. Removal of residue:
After you’ve removed the film, there may be adhesive residue left on the window frame. Use a cloth soaked in isopropyl alcohol or an adhesive remover to gently rub off the residue. Be sure to test the alcohol or adhesive remover on a small, inconspicuous area first to ensure it won’t damage the window profile material.

4. Scrubbing and cleaning:
If there is still residue, mix warm soapy water and use a soft cloth or sponge to scrub the area. You can also use a plastic scraper or your fingernail to gently remove any stubborn residue. Avoid using abrasive materials that may scratch the surface.

5. Rinse and dry:
Rinse the window profile with clean water to remove any remaining soap or adhesive remover. Dry the area with a clean, dry cloth.

6. Finishing:
If there are still small bits of residue or stubborn stains, you can carefully scrape them off with a razor blade. Make sure you hold the blade at a low angle and use it carefully to avoid damaging the window profile.

7. Final Cleaning:
Once the adhesive has been completely removed, clean the window frame with a glass cleaner or other suitable cleaning product to ensure it’s free of any residue or streaks.

**Important tips:**
– Work slowly and patiently to avoid damaging the window profile or leaving adhesive residue.
– Use gloves to protect your hands, especially when using adhesive removers or cleaning products.
– Test any chemicals (such as adhesive removers) on a small, inconspicuous area to ensure they won’t damage the window profile material.
– If you’re unsure or uncomfortable with the process, consider seeking professional help.

Remember that the effectiveness of these steps may vary depending on the type of film and adhesive used on your window profiles, so always exercise caution and start with the least aggressive methods.
