How To Clean uPVC Windows

As well as being known for its energy efficiency, soundproofing capabilities and security features, uPVC windows are very low maintenance.

uPVC window frames and sills are particularly durable. They will never rut or rust like wood or aluminium. However, dust and dirt will inevitably build up over time, which means you need to regularly wipe them down.

Here’s a few things to bear in mind before you clean your uPVC windows.


What materials should I use to clean uPVC?

It’s important that you stick to non-abrasive materials and products when cleaning uPVC window panes, frames and sills. You’ll be able to move a lot of the dirt with a sponge or soft cloth and warm soapy water, but specific uPVC cleaning products are guaranteed to shift stubborn layers of grime.

Do I need a professional to clean uPVC windows?

As uPVC is so low maintenance, you should be able to get your windows gleaming without the need for a professional, provided you use the right methods and cleaning materials. If you have any doubts about damaging your windows however, consult a professional window cleaner.

The Quick and Easy Way to Clean uPVC Windows

For the Hinges

Hinges are the trickiest part of a window to clean as they’re not very accessible, but here’s the easy way to do it:

  1. Start by opening the window as wide as possible, without damaging the hinge or encountering too much resistance.

  2. Use the nozzle of a vacuum cleaner to remove any dust and debris from the hinge mechanism. A nozzle with a soft dusting brush is perfect, as this will prevent you from scratching the surrounding area.

  3. If your window is a little stiff to open, it’s worth considering using a lubricant like 3-in-one® Multi-Purpose Oil to keep the movement of the hinge nice and smooth.

For the Window Panes

It’s a good idea to clean your window panes on a dry, cloudy day, as hot sunlight can bake streaks of cleaning product onto the glass before you’ve had the chance to wipe it off. Here’s the best way to get sparkling window panes:

  1. First, get rid of any dust and cobwebs from the panes using a dry brush or soft cloth.

  2. Using a sponge and a bucket of warm soapy water (washing up liquid works brilliantly) to gently wipe down the window panes until the majority of the dirt is gone. Avoid scouring pads, even for tough grime, as this can scratch the glass and the uPVC.

  3. Once dry, use a product like Windex to get the glass to really shine. For a DIY alternative, mix 1 tablespoon of white vinegar with 2 litres of water and spray onto the glass, then use newspaper to scrub it off.

Whiten and Brighten Your uPVC Frames

While uPVC window frames and sills are weather resistant, they can eventually gather dust and lose their lustre, but with the right cleaning method and materials, you’ll get them back to their original shine in no time.

You can use the same products and processes to clean both uPVC frames and sills:

  1. Use a dry brush or cloth to shift any dust or debris from the window frame or sill. Vacuum the corners to tackle hard-to-reach dirt.

  2. Wipe down the frame and sill with a sponge and warm soapy water to remove the initial layer of grime.

  3. If your window frames and sills are very dirty or discoloured, try using a safe and effective product like No Nonsense uPVC Cleaner or HG uPVC Cleaner. These will cut through the layer of build-up easily, without damaging the finish of your window frames.

Cleaning uPVC: Pitfalls to Avoid

Incorrect cleaning methods or products can easily cause irreversible damage to your uPVC windows by scratching them or removing their glossy finish. To ensure that you’re using materials appropriate for use, avoid the following:

  • Cream cleaners
  • Bleach
  • White spirits
  • WD-40
  • Scouring pads
  • Nail varnish remover
  • Methylated spirits

Anglian uPVC windows are resistant to the majority of everyday grime, so on top of saving you energy, they’ll save you time too.
