The major plus of PVCu doors and windows is the maintenance – or lack of it. Wooden frames can look great if they are well maintained, but how many of us have the time to do this well?  Painting and re-painting, sanding and weatherproofing are all time-consuming activities in a world in which time is the one resource we seem to be losing fast.

However, while PVCu doors and windows are easy to maintain, you still need to keep them clean. Mould and mildew can form on some parts but it is easy enough to remove, so there is no excuse. What the best way to do this? We’ll tell you now - but first, what not to do…

What NOT to do

-          Avoid any abrasive cleaning product or cloth

-          Do not try to paint the frames

-          Avoid scratching the frames, as they cannot be filled and painted like traditional wooden frames can. Handle with care!

Cleaning the frame

Opening the window reveals a channel where the locking system and hinges sit. Use a small brush of some kind to loosen the dirt and then vacuum any excess dust away. This simple exercise will allow the window to close fully and so reduce drafts to increase energy efficiency. Use a damp cloth to wipe down the rubber seals.

Cleaning the glazing

The glazing itself can be cleaned with any non-bleach soapy detergent. Use a non-abrasive cloth and clean both inside and out. Then wipe down with a dry micro-fibre cloth, just as you would your car windows. Use filtered water, if you have a filter at home, to avoid leaving any streaks – it sounds decadent but it really reduces the workload if you live in a hard-water area. If you have any paint splashes on the window, use a blade to remove stubborn spots but exercise extreme caution as any damage will be irreversible.

Solvents and creams

Any hardware store will stock the products you need, but be sure to check the label to ensure you don’t inadvertently damage your windows and doors. If you’re not sure, one of the staff members will be able to help you. These cleaners will often renew the frame as well, leaving the window as good as new. It’s an annual job, but much easier, cleaner and faster than painting.


Remember to lubricate all moving parts. This will make it easier to open and close the window, but also reduce the stress on the moving parts, meaning your window will last a lot longer. You can also spray some lubricant into the keyhole and work it in with the key to help with ease of opening.

Wood grain and bespoke finishes

WD40 is all that is needed on these finishes. It will give the frame a sheen, but be sure to wipe and dry well to avoid any fingerprints on the glass. However, do not use these on the white PVCu frames.

With all this said, it is important to note that while older PVCu windows can be brought back to life aesthetically, the technology has advanced so far that the energy efficiency of modern windows make it well worth the investment to upgrade. In addition to this, the aesthetic quality of the new windows has improved greatly, so even period houses are able to maintain a look that will keep all but the most traditional of owners happy.
