How to Clean uPVC: A Complete Guide
uPVC, or unplasticised polyvinyl chloride, is a popular choice for windows, doors, and outdoor fixtures due to its durability, low maintenance, and resistance to weathering.
However, over time, uPVC can accumulate dirt, grime, and stains that dull its appearance. Regular cleaning keeps it looking fresh and helps maintain the condition of the surface. Follow these straightforward steps to clean your uPVC safely and effectively.
Step 1
Gather Your Cleaning Supplies
Before you start, collect all the necessary cleaning materials. For basic cleaning, you’ll only need a few simple items.
For More Difficult Marks
✓ An old toothbrush for corners and grooves
✓ A purpose-made, non-abrasive uPVC cleaner
✓ Additional clean microfibre cloths
Avoid abrasive cleaners, scouring pads, bleach, solvents, or harsh chemicals, as these may scratch, stain, or damage the uPVC surface.
Step 2
Start with a Basic Clean
Begin by giving the uPVC surface a basic clean to remove loose dirt, dust, and grime.
1. Prepare the Solution
Mix warm water with a small amount of mild washing-up liquid in a bucket.
2. Wipe Down the Surface
Dip a microfibre cloth or soft sponge into the soapy water and gently wipe the uPVC. Work from top to bottom so dirty water does not run over areas you have already cleaned.
3. Rinse with Clean Water
Rinse the cloth or sponge in clean water and go over the uPVC again to remove any remaining soap residue.
4. Dry the Surface
Use a clean, dry cloth or towel to wipe the surface and remove remaining moisture and water marks.
Step 3
Remove Stubborn Stains and Marks
For more stubborn stains, such as bird droppings, grease, or scuff marks, a deeper clean may be necessary.
Purpose-Made uPVC Cleaner
For marks that do not lift with warm soapy water, use a non-abrasive cleaner specifically intended for uPVC. Apply it according to the manufacturer’s instructions and test it on a small inconspicuous area first if necessary.
Hard-to-Reach Areas
For dirt in corners and grooves, use a soft-bristled brush or an old toothbrush with mild soapy water. Gently loosen the dirt before wiping the area clean.
What About White Vinegar?
White vinegar is sometimes used when cleaning uPVC, but the correct approach depends on the surface and the cleaning method. Read our dedicated guide: Can You Use White Vinegar to Clean uPVC?
Step 4
Restore the uPVC Finish
After cleaning, thoroughly drying the surface will usually leave the uPVC looking much fresher.
If you want to use a specialist finishing product, choose one specifically labelled as suitable for uPVC and follow the product instructions carefully. Avoid general automotive polishes, abrasive products, or treatments that are not intended for uPVC frames.
Step 5
Clean and Maintain uPVC Frames and Fixtures
uPVC often appears around windows and doors where dirt can accumulate in corners, grooves, tracks, and other difficult-to-reach areas.
Dust First
Start by using a soft brush or cloth to remove loose dust and dirt from the frame before adding water.
Clean with Soapy Water
Use mild soapy water and a soft cloth or sponge to clean the frames, paying particular attention to corners and grooves.
Detail the Tight Areas
Use an old toothbrush or soft brush to reach small areas around window tracks, hinges, and door crevices.
Dry Thoroughly
Finish by wiping the cleaned areas with a dry cloth and removing any remaining moisture or cleaning residue.
Step 6
Keep Your uPVC Clean for Longer
Regular light cleaning makes it easier to prevent dirt and staining from building up.
Clean When Needed
Give the frames a light clean whenever dirt becomes noticeable rather than waiting for heavy staining to build up.
Remove Marks Early
Bird droppings, grease, mud, and other marks are generally easier to remove when they are dealt with sooner rather than later.
Check Moving Areas
Keep tracks, hinges, corners, and drainage areas free from dirt so that windows and doors can continue operating correctly.
Final Thoughts
Keeping Your uPVC Looking Its Best
Cleaning uPVC effectively requires only basic supplies, regular care, and occasional deeper cleaning for more persistent marks. Warm soapy water, soft cloths, and suitable uPVC cleaning products can help maintain the appearance of windows, doors, and frames without damaging the surface.
Regular upkeep also prevents dirt from building up in frames, tracks, and other difficult-to-reach areas, helping your uPVC continue to look clean and well maintained.
