  • How to clean uPVC doors

    Here are a few easy steps to clean your uPVC doors:

    If your uPVC is still in warranty, take extra care when cleaning your uPVC doors.

    1. 1

      Open the door

      Open the uPVC door as wide as it will go.

    2. 2

      Remove loose dirt and debris using a vacuum

      The ideal choice is to use a brush nozzle on your vacuum. If you don’t have a brush nozzle, attach a toilet roll cardboard tube. These can be cut or bent to shapes to fit the slots around the uPVC door. Use the vacuum to clean around the inside of the door frame, paying special attention to the nooks and crannies in the corners and around the locking mechanism.

    3. 3

      Create a white vinegar and warm water solution in a spray bottle

      Use one cup of white vinegar with four cups of warm water in a spray bottle to clean the frames.

    4. 4

      Leave to soak for ten minutes then wipe

      Leave it to soak for ten minutes before wiping down the frames with a soft cloth.

    5. 5

      Clean regularly

      Ensure that you clean regularly, especially if you have sliding doors which could be affected by a build-up of dirt.

    When cleaning your uPVC doors, avoid material and products such as:

    Scouring pads

    White spirit


    Iron wool

    3. 3

      Always keep your eyes open when cleaning uPVC window frames. Mould can easily build up and should be thoroughly removed to prevent it spreading and getting worse

Use a clean rag or paper towel to remove the mould from the surface. Allow your windows to get a regular flow of fresh air, to keep the area free from damp and prevent mould from building up.

    5. 5

      Clean the window panes

      Mix a bowl of warm water with a few drops of washing-up liquid. Wipe the window pane with the soapy water and a soft cloth or sponge. Remove excess water with a dry towel, kitchen roll or rag. Mix 2 cups of water with ¼ white vinegar and ½ cup of washing-up liquid. Dip newspaper into the mix and wipe the window panes in a circular motion. This will give you a smear and streak-free finish.

      Avoid using cream or other abrasive cleaners as they could scratch the uPVC.
