How to maintain uPVC windows

15th January 2020 |

uPVC Windows

uPVC windows have a range of benefits which has resulted in them being the most popular window choice in the UK. One of the biggest selling points is that they offer an almost maintenance-free solution. Unlike other commonly used materials, there is no risk of rotting or rusting. However, from time to time your uPVC windows will still need a little TLC. The good news is maintaining them will not require any specialist tools or equipment.

What you will need:

  • A bucket of warm water
  • Washing up liquid
  • Clean sponges and cloths
  • Brush
  • uPVC window cleaning solution

Cleaning the glass

Cleaning the glass on your windows is not a task that will need to be completed very often. As a rule of thumb, it is best to clean your windows when you can physically see that they are dirty. However, we would recommend giving them a clean down at least every two months.

It is best to avoid cleaning them in direct sunlight as hot sunlight can leave a streaky finish. Opt for a dry cloudy day to ensure you get the best clean possible. If you have uPVC tilt and turn windows you can easily do this from the inside of your property. Follow the below steps to get clear and sparkling windows;

Pre-clean – Its best to start by giving your uPVC windows a good wipe down with a soft cloth to remove any dust, cobwebs or excess dirt. Always use a non-abrasive cloth to avoid scratching the glass.

Windowpane clean – Cleaning your windows is as simple as using a sponge and warm soapy water to gently wipe down the pane of your windows. If you have a build-up of dirt, it’s important to not use any force or abrasive material as this can damage the glass and the uPVC frame. If you prefer to use a glass, cleaner consider one which offers a streak-free finish.

For harder to reach areas you might consider investing in a window cleaning pole, which can be bought online for a reasonable price.

Cleaning the frame

Clean and bright window frames can do wonders for increasing the attractiveness of your property. The most common uPVC window frames are white and although they are extremely weather-resistant, dirt and grime can build up over time.

Just like cleaning the windowpane, all you will need is a sponge or a white cloth and warm soapy water. This should be enough to lift any stains and dirt which might have built up. For a deeper clean of your uPVC windows, you might consider using a uPVC cleaner. Always choose one from a reputable provider to avoid any irreversible damage to your uPVC windows.


What you will need:

  • Cloth
  • Silicone spray – such as WD-40

Getting your windows shining and looking bright is just one part of the cleaning process. It’s important to pay attention to the hardware such as handles, locking systems and hinges. This will ensure they continue to function correctly and reduce stiffness.

Hinges – With your windows open, carefully spray your lubricant onto the hinges and locking mechanism. From here open and close the window to ensure the lubricant is distributed fully. Using a cloth, wipe away any excess liquid to avoid contact with your uPVC frame and glass window.

Handles – Apply a small amount of lubricant to your key and insert it into the handle lock. Carefully move it in and out of the lock and gently perform a lock and an unlock movement.

What to avoid when cleaning your uPVC windows

When cleaning your uPVC windows it’s important to keep in mind that a gentle approach is the best one. Excessive force, using unsuitable chemicals or abrasive materials can cause irreversible damage.


  • Bleach, as this can cause discolouration which can not be rectified
  • Cream cleaners as these can be abrasive and cause scratches
  • Abrasive materials such as scouring pads and wire wool as these can cause damage to both the windowpane and frame
