How To Clean uPVC Window Frames

The process of cleaning your uPVC windows should be fairly simple. You will only need a few items, several of which you likely already have lying around the house! We have broken the process down into steps to make the task as easy as possible for you.

You Will Need:

1. Wash Off Dirt And Debris

Mix hot water and a few drops of dish soap together in a bowl. Wet your non-scratch sponge with the mixture and start wiping away any dirt and debris from your window frames. Once you are satisfied that your frames are clean, rinse any suds away with plain water. If you are cleaning your frames from the inside, use a dampened cloth instead of a wet sponge for this step to avoid flooding the house!

2. Dry The Frames

Use a soft rag or towel to dry off the frames before proceeding to the next step. If you are washing your window frames from the outside and the weather is good, you can also allow them to air dry.

3. Buff The Frames

This step will add a layer of protection to your window frames that should prevent them from getting dirty as quickly. Apply a small amount of car wax to your microfibre cloth and gently rub it onto your dried window frames. Once you have covered the frames, use a clean section of your cloth to buff off the wax.

How To Clean Inside uPVC Window Frames

The insides of your window frames can get surprisingly dirty with a collection of debris and cobwebs. Accumulated over time, this can make it difficult to open and close your window, which is why it’s important to clean out the insides of your uPVC window frames. Here is a guide on how you can do this:

You Will Need:

  • Warm water
  • A bowl
  • Dish soap
  • A clean cloth
  • A vacuum cleaner (brush attachment)
  • A light oil spray

1. Remove Dirt And Debris

To begin this procedure, open your windows fully and use your vacuum cleaner to remove any debris such as cobwebs, dust or dirt from the inside of your window frames.

2. Clean With Soap And Water

Once the insides of your window frames are free of debris, you can proceed to wipe them down using a cloth and a mixture of warm water and dish soap. Make sure to clean the entirety of the inside of the frame without neglecting any small crevices.

3. Dry The Insides Of The Frames

Use a clean, dry cloth to absorb any moisture from the insides of your window frames.

4. Maintain The Metalwork

Use a light oil spray to maintain the handles, hinges and locking systems within your windows. This should be done every six months to preserve their longevity. It is essential for the safety and security of your home to ensure that your windows are in good working order. If the hinges on your windows are stiff, this can obstruct your escape route in the event of an emergency. If the locks on your windows are broken, it becomes easier for burglars to break in. This article by Cement Answers will inform you on how to lubricate your window hinges, as well as warn you against products you shouldn’t use on uPVC window frames, such as WD40.
