Cleaning painted UPVC is really easy, so if your doors or windows happen to collect dirt or traffic film over time, don’t worry about it. Dirt and heavier soiling can be safely removed in minutes with the right tools and technique.
Here’s what you need:
Removing dirt and grubbiness
Dirt and grubbiness can be removed from painted UPVC with a soft telescopic washer if you have one (a soft bristle brush connected to a low flow hose) or you can use a sponge and a mild detergent to gently agitate the dirt and lift it away from the surface. A car shampoo will work excellently if you have it lying around.
It’s important to use a PH-neutral detergent and not to let it sit on the painted UPVC for more than 5 minutes. Work the brush or sponge with your hand and rinse away the suds to check your work. Repeat as necessary.
Removing bird lime
Bird lime should be removed as soon as it is discovered because it’s acidic and if left to fester it can damage paint. Remove it by placing a wet paper towel over the soiling. Let it wet the lime and then lift it away with the towel. You can also safely remove bird lime with a bird lime neutraliser designed for cars.
Removing traffic film
If you live close to a busy road, it’s likely your UPVC will collect a layer of traffic film. This won’t damage the paint, but it will dull the finish.
To effectively remove traffic film, the best product to use is a non-caustic traffic film remover designed for car paint. This will have the correct ingredients to cut through the film without damaging the paint beneath.
You can buy 10L jugs of traffic film remover for around £20. Whether the product is designed for a pressure washer or not doesn’t matter. You will create suds in a bucket with a warm tap and use a sponge to apply it to your UPVC. Let the suds sit for 5 minutes before sponging it and finally rinsing it off.
Your UPVC should now be gleaming and as good as new.
