UPVC became the most popular choice for windows when it was introduced in the 80s, mainly because it was a welcome maintenance-free option for wooden frames. While wood requires a lot of maintenance, PVC windows can tolerate years without attention.
However, uPVC needs regular washing to keep it looking fresh and shiny, as dust and dirt accumulate, especially on white frames. For properties in towns, cities, or near the coast, it is recommended a good cleaning every three months, and for rural areas that don’t experience so much dirt and weather, twice a year should suffice.
Below described are the best ways how to clean upvc properly your PVC windows and doors.
How to Clean the Inside of PVC Window Frames
- Start by cleaning the hinges and the inside of the frames.
- Open the window to the maximum up to the resistance point (do not exceed this point).
- Use a vacuum cleaner to vacuum any dust buildup from the hinges.
- Use a vacuum attachment with a soft brush to go around the frame and get into all frame corners.
- Use a soft cloth and warm water with a mild soap solution to clean the inside of PVC window frames.
- Keep the hinges lubricated with a few drops of multi-purpose oil.
How to Clean UPVC Window Frames
To avoid any discoloration or damage caused by too vigorous cleaning trying to move stubborn stains, regular washing with warm soapy water will keep your white PVC window frames in top condition.
- Use a soft brush or soft cloth to remove dust and dirt.
- If you have a hose, rinse the windows with clean water to remove dirt.
- Prepare a soap solution in warm water with a squirt of dishwashing liquid or a dedicated liquid glass cleaner in a bottle (not the spray type).
- Use a soft cloth and soapy solution to wash the frames and the glass.
- DO NOT USE a scouring pad, wire wool, or sponge with a scouring surface.
- If you have a hose, rinse again with clean water.
The secret to getting crystal clear windows is to use a quality squeegee with a soft blade (like window cleaners do). Start from one side and sweep side to side down or start from one side and sweep up and down, then use your fingers or a cloth to wipe excess water from the squeegee before the following scan.
Make a Window Cleaning Spray
To achieve a gleaming finish, you can use a specific window cleaning spray with a soft cloth, then rub it with a paper towel or an old newspaper. But DO NOT spray this on the frames.
- You can also use vinegar – it’s a magic ingredient for home cleaning.
- Mix ½ cup of vinegar with 2 cups of water and a few drops of dish soap.
- Use a soft cloth to apply to windows, then use an old newspaper to rub in a circular motion to dry to a glossy finish.
How to clean PVC doors
To clean your PVC doors, use the same process as cleaning your PVC windows.
- Vacuum the inside of the frame and hinges
- Brush off the dirt
- Use a lukewarm soap solution
- Rinse with clear water
How can I make my uPVC white again?
Old white PVC frames and cheap PVC are known to yellow with age. Unfortunately, there’s not much you can do to restore the whiteness if it’s a quality issue.
As mentioned above, if the frame has been damaged by an abrasive product, scouring pad, or years of using a cleaning cream, the PVC will be full of fine scratches that will cause the frame to look dull and discolored. If this has happened, there is nothing you can do that will make the edges look white and shiny again.
If the frames are discolored from years of grime and dirt, you can try another magic trick with vinegar.
- Mix 1 cup of vinegar with 4 cups of hot water
- Use a spray bottle to spray on the uPVC
- Leave this for 10 minutes
- Use a clean, dry cloth to wipe
- NEVER use bleach or white spirit as this will damage the surface of the uPVC.
Never be tempted to use a scouring pad, wire wool, or anything rough with too much pressure, as this can scratch and permanently damage the surface of the uPVC.
Many detergents contain hidden dyes, and PVC is porous; it can react and permanently stain your window frames. And no, you can’t bleach them again.
