UPVC window frames are a great addition to your home, but they are just as vulnerable to mechanical scratches as any other window frame.
Removing scratches from UPVC window sills at home
You can easily polish the surface of plastic windows to remove most shallow scratches. Deeper scratches require more professional care, or in the worst case, replacement. This doesn't mean that plastic windows are bad, in fact, today's plastic windows are as efficient and economical as glass windows. Plastic windows are lighter than glass windows of the same size and can withstand the worst weather conditions. While neither plastic nor glass windows are completely scratch-proof, they both have good scratch resistance.
Cut and polish method
You'll want to keep your uPVC doors and windows looking neat and clean, but scratches are common. Don't worry, scratches can be easily removed with a few simple methods. Simply remove any minor scratches with 1000 or 1200 grit wet or dry sandpaper, then cut and car polish. Depending on the scratches, you can start as low as 80 grit and progress to finer wet and dry grades. This will remove most of the uPVC.
Properly cleaning and sanding your uPVC doors and windows will keep them looking brand new without damaging their appearance. You can work your way up to 120 grit sandpaper, then 240, 400 and 600 grit until all the scratches are removed. As a final step, take precaution by sanding again with 800 grit or 1000 grit sandpaper, and then 1200 grit sandpaper for any smaller scratches that have occurred.
How to Remove Scratches from Smooth uPVC Plastic Window Frames
We need to note that even if some scratches appear on the plastic, we should not be discouraged. To remove these scratches, we can use some simple methods. Just like removing scratches from other materials, we can use a polishing compound and a rag or a polishing wheel together. Palm sanders can also be used with wet or dry sandpaper to remove scratches, but be sure to be extra careful (or ask an expert to help).
We can start with coarse sand and then gradually follow a gradient down to the finest sand. Be sure to keep the surface wet throughout the process. Finally, we can gently polish it with some T-cuts, and our uPVC windows will be brand new.
