Do your uPVC window frames look dull or discolored? Over time, even the highest-quality uPVC windows can accumulate dirt, grime, and stubborn stains. But with the right cleaning techniques, restoring the fresh look of your uPVC frames can be easy and hassle-free. In this comprehensive guide, you'll discover industry secrets, proven methods, and expert tips for cleaning uPVC window frames and keeping them sparkling white all year round!
Why Is Cleaning uPVC Window Frames Important?
Untouched window frames not only look unsightly but can also diminish the value of your property. uPVC (Unplasticized Polyvinyl Chloride) is a fantastic material for windows due to its durability, low maintenance, and energy efficiency. However, if left unattended, uPVC can gather:
- Dirt and dust from the outdoors
- Mould and mildew in damp areas
- Staining from smoke, pollution, or bird droppings
- Greasy marks and fingerprints
How Often Should You Clean uPVC Window Frames?
The frequency of cleaning your uPVC window frames depends on your location and exposure to the elements. In city environments or coastal areas, windows may collect debris and salt much faster. For most homes, it's smart to:
- Wipe down exterior uPVC frames every 1-3 months
- Clean interior window frames every 3-6 months
- Perform a deep clean annually (or as needed for stubborn stains)

- Warm water
- Soft non-abrasive cloths or sponges
- Old toothbrush or soft-bristled brush for corners and hinges
- Spray bottle (optional for gentle application)
- Microfiber cloth for drying and buffing

Advanced Tips and Industry Secrets for Cleaning uPVC Window Frames
How to Restore Yellowed uPVC Frames
A common concern is yellowing uPVC window frames. This is often caused by UV exposure, age, or nicotine smoke. While old, deeply yellowed uPVC may need professional restoration, you can try these techniques:
- Baking Soda Paste: Apply a thick paste of baking soda and water, allow to sit for 15 minutes, and gently scrub.
- Cream Cleaner: Use a non-abrasive uPVC cream cleaner (available from hardware stores) for light discoloration. Always read product instructions.

Note: Do not use bleach or harsh solvent-based cleaners, as these can make yellowing worse or cause brittleness.

- Spray the solution onto the mouldy areas and allow to sit for 10-15 minutes.
- Wipe clean with a damp cloth and dry thoroughly.
- For more stubborn growth, repeat or use a small amount of hydrogen peroxide.
Always wear gloves and ventilate the area when dealing with mould or mildew.
Tips for Cleaning Inside Tricky Corners and Hinges
- Use an old toothbrush, cotton swab, or wrap a thin cloth around a butter knife for narrow spaces.
