Mild weather and plenty of free time during this part of the year are perfect for a good house clean up. Plenty of sunlight also makes our beautiful double glazed windows show every little speck of dirt. This guide will show you how to properly take care of uPVC windows.

Should I clean them at all?

When done properly, double glazing can improve the value of the property in more than one way. It improves energy efficiency, making the home more environmentally-friendly and lowering the heating bills in the process.

Secondly, it makes your home look more presentable and easier to sell. But still, if you want them to look as new, you’ll have to give your double glazed windows a good scrub. Surprisingly, many people are afraid of damaging their uPVC windows, so they don’t clean them at all, or give them just an occasional light swipe. But rest assured, your double glazed windows are robust enough to withstand a good cleaning any day.

The right cleaning method

When it comes to cleaning your uPVC windows, the procedure is basically the same as with any other glass surface. The best way to do it is using a cloth and a window cleaning product or just simple soapy water. You can achieve a streak-free finish when the surface dries up if you add a cup of white vinegar to the water.

If you have patterned window panes, use a soft bristle brush to remove the dirt from the crevices. After you wash them, remove any remaining water using a squeegee with a rubber strip to prevent streaks.


Tip: There is a variety of steam and vacuum cleaners designed specifically for cleaning uPVC windows. Not only are they safe for your uPVC glazing, but they can give much better results for much less work, and even deal with condensation.

Cleaning the frames

Once you are through with cleaning the panes, you need to take care of the plastic frames, too. Cleaning them is much simpler than you may think. Open your window and use the brush attachment on your vacuum cleaner to lift any dust and debris that may have gathered in the corners and crevices.

After that, wipe down the frame using a sponge and warm soapy water. Avoid using the rough side of the sponge as it can scratch the plastic. Proceed to dry the frame using a soft cloth, a kitchen roll, a microfibre towel or a chamois leather.

Soap vs. brand cleaners

While soapy water can clean your window frames, sometimes it won’t give your double glazed thermal windows that virgin white frame look as if they are new. In that case, you can use some of the proprietary brand cleaners that are designed especially for uPVC, and avoid scouring pads with products that contain bleach, solvents or abrasive components.


Cleaning between the panes

If moisture or dirt starts to build up between the two panes, this indicates that the airtight seal that gives the window its insulating properties is broken. Although there are some makeshift methods to clean the inside space, the real cleaning requires taking apart the window. This would definitely break the seal, voiding the warranty, and re-sealing the panes is not possible without hiring professionals.

Aside from insulating your home from outside heat, cold and noise, double glazed windows increase the value of your home. Still, in order for them to look attractive and new, you need to clean them regularly. They are made with premium materials and a little soapy water and a gentle scrub will do the trick.
