Window frames turning yellow with age? Discover the most effective remedies for returning them to looking nearly new

PVC window and door frames are amongst the most common in modern homes: if they are of good quality, they offer thermal insulation without excessive expense, and also require very little maintenance. However, this does not mean that over the months and years they do not become covered with a film of dirt, both indoors and outdoors, which in the long run alters their appearance.

Furthermore, very often the window frames start off as white, sometimes even on the outside, and in that case, in addition to dirt, there is also a progressive yellowing of the finish. Being able to counter this phenomenon is not always easy, but there are methods that help to thoroughly clean the window frames. Find out more by reading further:

Creativo

• Open the windows fully, and with the help of a vacuum cleaner remove all the dirt that is in every crevice and corner that is difficult to reach by hand. If you have a brush attachment with long bristles, it will help you a lot and without running the risk of scratching the PVC.
• Fill a bucket or basin with warm water and add half a glass of dish soap.
• Use a soft cloth to clean the entire surface of the fixtures and frames, so as to remove all the greasy dirt and dirt deposits. Never use abrasive sponges, pads or accessories.
• Use a soft cloth or other dry microfiber cloth (even old T-shirts or kitchen paper will do) to remove excess water.

At this point you should have a clear picture of the coloring of your fixtures: if you still notice some yellowish stains, you can try to solve it in the following way:

• Mix 100ml of white vinegar in one liter of hot water and pour it into a spray bottle.
• Spray on the yellowed area and leave it to act for 10 minutes.
• With a soft, dry cloth, wipe off to remove excess moisture.

A useful alternative can be to use wet wipes (i.e. those used for children), which are naturally very delicate. Vinegar should only be used infrequently and in a very diluted form, as it could ruin the glossy finish of the PVC. In any case, never resort to using cream products.

If you notice that there are areas of dirt or stains that do not come off even with these methods, you will have to try one of those products specifically made for cleaning PVC.
