How To Clean Your Double Glazed Windows


Double glazed windows are the ideal choice for keeping a property warm, quiet and as secure as possible. Not only do double glazed windows reduce draughts and prevent damp, but they also maximise energy efficiency – saving you money on heating expenses. Like all windows, double glazed windows need to be cleaned regularly in the correct way to reduce the risk of mould growth and avoidable deterioration. Find out the right way to clean your double glazed windows with our helpful guide!

Step-by-step cleaning for your double glazed windows:

Everyday cleaning of double glazed windows is quick and easy yet effective to keep them in tip-top condition for as long as possible.

  1. Choose the right cleaner

Firstly, you will want to choose the right cleaner for the job. If you pick up the nearest cleaning liquid, you could seriously damage your double glazing windows. Get your double glazed windows sparkling clean again with a simple homemade cleaner using one-part white vinegar and four-parts water.

To apply the homemade cleaner, use an empty spray bottle for ease and then wipe the solution in a circular motion with a microfibre cloth. The circular motion prevents any streaks being left behind and the microfibre cloth is gentle enough to clean without the risk of making any marks.

  1. Vacuum or clean with a damp cloth first

If it’s been a while since you’ve cleaned your double glazed windows, you might need to give them a quick vacuum first. This removes excess dust and creates a smooth surface for you to clean effectively. If you’re struggling to reach the corners, try using an old toothbrush!

  1. Use newspaper

Another top tip to avoid leaving any cleaning streaks behind is by using newspaper to wipe away any residue and leave your windows sparkling.

How to maintain UPVC windows:

Casement windows, also known as uPVC casement windows, provide extra security and warmth to any property. uPVC casement windows are a popular choice as they are inexpensive and effective in eliminating draughts and conversing energy in any property.

  • How do you clean the rubber seals on double glazed windows?

uPVC double glazed windows are designed with a rubber seal between the two panes of glass. Keeping the seals in good condition is important to prevent mould and improve the overall condition of your windows. To clean the uPVC window seals, use warm soapy water rather than traditional cleaning products, as these can cause the rubber to tear.

  • How to prevent and deal with condensation between double glazed windows

If the seal in a uPVC window is broken or damaged, you might start to notice condensation within the window. Condensation can also be caused by the surface temperature of the window being cooler than that of the air inside the room. Condensation in double glazed windows should not be left untreated as it can lead to more serious problems, such as black mould in the surrounding walls.

To prevent condensation between your double glazed windows, you should check the seals each time you clean. If you notice any problems, you might need to get the seals replaced. At Notaro Windows, we offer a 10 year guarantee on all our uPVC windows for complete peace of mind.
