Why Is My uPVC Window Frame Turning Yellow?
Although plastics are known for their durability, their appearance and properties can be negatively affected due to prolonged or regular exposure to UV light and heat. That’s why the most common cause of yellowed uPVC windows is sunlight, and windows in parts of the house that get the most direct sunlight during the day are most likely to turn yellow.
But this isn’t the only possible reason for yellow stains on your uPVC windows. Using cleaning detergents with abrasive additives is another one. There’s also a chance that your window frame has been, at some point, contaminated, e.g., with mounting foam or other chemical substance.
It’s worth noting that uPVC window frames made of low-quality material are more susceptible to yellowing. That’s why it’s best to choose products from reliable manufacturers, especially when choosing roof windows, such as PVC centre pivot roof windows or flat roof windows, that will be constantly exposed to the sun.

How Do You Make Yellow uPVC Window Frames White Again?
You can clean yellow uPVC windows with a store-bought uPVC cleaner and yellow stain remover or homemade cleaning solutions. If you choose the second option, there are several methods you can use:
Soap and water: Combine soap with warm water and gently clean the window frames. If you act quickly and the stains are not too stubborn, this may be enough to remove them, so it’s a good first step to try.
White vinegar: White vinegar is an effective and ecological alternative to chemical cleaning solutions. Mix a few spoons with a bucket of warm water and clean the yellowed uPVC surface.
Baking soda: Baking soda is another popular ingredient of homemade cleaners as it can be used not only to clean but also to remove unpleasant smells. Mix baking soda with water until it reaches the consistency of a paste you can easily spread on the window frame. Use a soft cloth to rub the paste gently into the surface.
Always rinse and dry the window with a clean towel or cloth after using any cleaning solution.
How Do You Remove Stubborn Stains From uPVC Window Frames?
If homemade cleaning solutions fail, you can try using specialised uPVC cleaners. Never use bleach or chemicals, as they are not only ineffective against yellow stains but can further damage your windows. Some old and stubborn stains can be very difficult or even impossible to remove, so preventing them with regular cleaning and the right detergents is crucial.
How to Clean uPVC Windows
There’s not much you can do about weather conditions, but choosing the right detergents and methods of cleaning PVC window frames is something you can easily do. Here are a few helpful tips:
- Clean your windows regularly. It’s much easier to prevent yellow stains from forming than to remove them.
- When using a store-bought detergent, always check the product label to make sure it doesn’t contain bleach or other chemicals that may end up damaging the window frame.
- Use a soft cloth or sponge. Avoid scouring pads and brushes that may scratch the surface.
- Don’t use glass cleaners to clean window frames. They often contain ingredients that should not be used on uPVC, such as ammonium hydroxide.
