How To Remove Scratches From UPVC Window Sills

Everything you need to know about how to remove scratches from uPVC window sills.

uPVC window frames are a great addition to any home, adding aesthetic appeal to your property. However, uPVC window frames are, unfortunately, no less susceptible to damage than most others.

Although uPVC is remarkably resilient and durable, it can still be scratched and pitted by mechanical means.

For example, if you accidentally scrape a mortar trowel on the window frame while plastering your room, you can expect a scratch to appear.

Removing Scratches From UPVC Window Sills At Home

You can buff the surface of a plastic window to remove most surface scratches, but deep scratches will most likely require more intense work, or in worst case scenarios, a replacement.

This is because manufacturers now have the ability to create efficient and inexpensive residential plastic windows that compete with glass window designs.

A plastic window is made to endure severe weather conditions and weighs half as much as a glass window of equivalent size.

Although neither glass or plastic windows are scratch-proof, they are both scratch-resistant in certain ways.

The Cut Polish Method

Simply clean out any minor scratches with a 1000 or 1200 grit wet/dry sandpaper, then finish off with a cut and then car polish.

Depending on the scratch, you might start as low as 80 grit and advance to finer wet n dry grades.

This would remove a lot of uPVC, but maybe not all of the scratch. You can then move up to 120 grit, then 240, 400, and 600 before removing all of the scratch.

As your last steps, take precaution and go over it again with an 800 grit or 1000 grit before blending in any smaller scratches from sanding with 1200 grade.

How To Remove Scratches From Glossy uPVC Plastic Window Frames

It’s important to note; the general rule with plastic is that if you can feel the scratch with your fingernail, it is probably too deep to remove with polishes.

Generally speaking, removing scratches from plastics is similar to removing scratches from most other materials. You can use a compound with a cloth or a buffing wheel.

It is possible to remove the scratches with wet and dry paper using a palm sander, but you must be extremely cautious. (Or call in the experts, Foreman Snags).

Start with a high grit then gradually move your way down the gradients to the finest grit. 

Make sure you keep the surface wet with water. Finally you’ll need to buff it very gently with some T-cut. This will make your uPVC windows look new again. 

Compounds That Help With Removing Scratches From UPVC Windows

T-Cut, Brasso or even Silver Polish are all easy to get hold of and effective for the task at hand here. This is because they all have slight abrasive qualities designed to remove scratches and residue.

The second part of this, as highlighted above, is to get to work on polishing the surface once you’ve introduced the abrasive compounds.

Three Steps To Repair Scratches On Your UPVC Window Sills:

  1. Wipe the plastic window surface with a combination of warm water and liquid dish soap to clean it. Clean the plastic surface using a soft cloth, paying special attention to the scratch marks. Paper towels and abrasive cleansers that might harm the plastic surface should be avoided.
  2. Squeeze a few drops of brass cleaner onto a soft microfiber cloth and dab it on the scratch. Gently rub the scratch with a circular buffing motion, using a little bit of brass cleaning solution. The cleaning compound fills tiny cracks, while the careful rubbing method polishes the plastic surface.
  3. Wipe the residual brass cleaner away with a clean cloth. If the scratch remains, apply another coat of brass polish and gently rub it into the plastic with your finger. Continue buffing in a circular pattern until the scratch is gone.
