How to Maintain uPVC Windows
uPVC windows have a range of benefits which has resulted in them being the most popular window choice in the UK, and rightly so. They don’t rot, rust or flake like timber or aluminium and are far more resilient to the ever-changing British weather. But just like anything that’s used every day, they’ll benefit from a bit of TLC now and then.
Grime and dust naturally build up around windows, especially near the hinges, vents and bottom edges where rainwater can collect. The good news is you don’t need any harsh chemicals or fancy sprays. For most uPVC windows, all you’ll need is:
- A bucket of warm water
- A small splash of washing-up liquid
- A soft cloth or sponge
- A dry microfibre cloth to finish
Start with a quick wipe-down of the frame and sill to remove cobwebs or loose dirt. Then gently wash the frame and glass with your soapy water, using long, light strokes. Avoid anything abrasive like scouring pads or cream cleaners, which can dull the surface or scratch the glass.
Finish by drying the glass with a clean cloth or window squeegee to prevent water spots. A cloudy day is ideal for this, as too much direct sunlight can cause streaking before you’ve had a chance to finish wiping down.
How Often Should You Clean Them?
It depends on where you live. In towns and cities or coastal areas, grime can build up faster. A clean every couple of months is usually enough to keep everything looking fresh, though there’s no harm in doing it more often if your windows are exposed to the elements.
For upstairs windows or hard-to-reach spots, tilt-and-turn window styles can make things much easier. If you don’t have these, a telescopic window pole can help you safely clean from ground level.
Keep the Frames Looking Like New
White uPVC frames are designed to resist fading and yellowing, but they still benefit from the occasional freshen-up. For light marks, your usual warm soapy water should do the trick. For more stubborn stains, you can use a dedicated uPVC cleaner. Make sure it’s from a reputable supplier and always test it on a small, hidden area first. If your frames have a woodgrain effect or coloured finish, always double-check that your cleaning solution is safe for foiled or coated uPVC.
Don’t Forget the Moving Parts
Getting your windows shining and looking bright is just one part of the cleaning process. It’s also important to pay attention to the hardware such as handles, locking systems and hinges. If they’re not maintained, they can become stiff or noisy over time, especially in colder weather when metal parts contract slightly.
You’ll need:
- A soft cloth
- A silicone-based spray
With the window open, lightly spray the hinges and locking mechanism. Open and close the window a few times to help spread the lubricant, then wipe away any excess to avoid streaks or residue on the frame.
You can also add a small amount of lubricant to your window key and gently move it in and out of the handle lock. This can help keep internal parts moving freely and reduce long-term wear.
Check the Seals and Drainage
Your uPVC windows are fitted with rubber weather seals that help keep draughts and water out. Over time, these seals can wear down or loosen slightly. Once or twice a year, check for signs of damage, cracks or gaps. Replacing a worn seal is relatively simple and can have a big impact on how warm and energy-efficient your room feels.
Most uPVC windows also include built-in drainage slots near the bottom. These are designed to let water escape, but they can occasionally get blocked by dirt or debris. Use a small soft brush or even a cotton bud to gently clear them.
What to Avoid When Cleaning Your uPVC Windows
When cleaning your uPVC windows, it’s important to keep in mind that a gentle approach is the best one. Excessive force, using unsuitable chemicals or abrasive materials can cause irreversible damage.
Avoid:
- Bleach, as this can discolour uPVC permanently
- Scouring pads or steel wool, as these will scratch the surface
- Cream cleaners, as these can be too abrasive and cause scratches, especially on textured or woodgrain finishes
- High-pressure washers, as these can damage seals and push water into places it shouldn’t go
