How to clean uPVC windows

uPVC is very easy to clean. It's a low-maintenance product that can handle all types of weather, be it high winds on a coastline or the smog of the city; but as with all things, it'll eventually build up dust and dirt over time.

To clean uPVC windows and conservatories:

1. Open the window and vacuum in all of the vents, nooks and crannies to remove any dirt or grime. If your hoover has a brush nozzle, use this to prevent scratching the uPVC. This window and conservatory cleanliness aids with the drainage of any fluid that may build up in the frame.

2. Using a bucket of warm soapy water (washing up liquid does the trick) and a sponge, wipe down the dirty window or conservatory. Avoid scouring pads, as they can scratch the uPVC, especially if you have a decorative finish.

3. You can dry your windows or conservatory with a tea towel, kitchen roll or an old rag, as long as it's clean and non-abrasive.

4. For crystal clear windows or a conservatory, try using newspaper to remove smears from the glass.


Things to avoid:

  • Bleach
  • White Spirits
  • Methylated spirits
  • Nail varnish remover
  • WD40
  • Applying too much pressure to the uPVC when cleaning
  • Scouring pads

All of the above can have a damaging effect on your uPVC windows or conservatory. The liquids above can discolour, erode or remove the finish, so be extra careful if you are using these near your products.
