Step-by-Step Guide to Cleaning and Maintaining uPVC Window Frames

What You'll Need

Soft cloths or microfibre towels
Mild, non-abrasive liquid soap or detergent
Bucket of warm water
Soft-bristled brush or old toothbrush
Spray bottle (optional)
Vacuum cleaner with brush attachment (optional)
Squeegee
Lubricant for hinges and locks (like silicone spray)
Cotton buds

1. Dusting and Vacuuming the Frames

Start by removing loose dust and debris from your uPVC window frames:

Open the windows fully to access all sides of the frame.
Use a vacuum cleaner with a brush attachment to gently remove dust, cobwebs, and loose dirt.
Pay special attention to corners, hinges, and sliding tracks -- these trap the most dirt.
Cotton buds are excellent for tight spaces where dust collects.

2. Preparing a Gentle Cleaning Solution

For spotless uPVC window frames, never use harsh chemicals or abrasive cleaners--they can damage the surface and cause discoloration.

Mix a few drops of mild liquid soap or washing-up liquid with warm water in a bucket.
Avoid bleach-based products, ammonia, or cream cleaners.
If needed, pour the mixture into a spray bottle for easy application.

3. Cleaning the Frames

With your cleaning solution ready:

Dip a soft microfibre cloth into the soapy water and wring it out.
Gently wipe over all visible and hidden frame surfaces, applying more pressure only where there is stubborn grime.
Use a soft-bristled brush or an old toothbrush for corners, joints, and weather strips to dislodge dirt.
For tough stains (like grease or pen marks), make a paste of bicarbonate of soda with a little water, apply gently with a soft cloth, and rinse.
Never use abrasive pads or steel wool as these will scratch the uPVC surface.

4. Rinsing and Drying

Once cleaned, take another clean damp cloth and wipe away any soap residue from the frames.
Finish by drying the frames with a lint-free towel to prevent watermarks and streaks.
For a dazzling finish, buff with a dry microfibre cloth.

5. Cleaning the Glass Panes

Clean glass can make your uPVC windows look freshly installed. Follow these steps:

Spray the glass with vinegar solution (50% vinegar, 50% water) or a specialist glass cleaner.
Wipe with a clean, soft cloth or use a squeegee for a streak-free finish.
Don't forget the edges where glass meets the frame.

6. Cleaning Window Tracks and Hinges

Vacuum tracks and hinges to remove debris.
Use a soft-bristled brush and your cleaning solution for deeper cleaning.
After drying, apply a small amount of silicone spray lubricant to moving parts to keep them operating smoothly.

7. Polish and Condition Your uPVC Frames (Optional)

Apply a specialist uPVC cream or restorer once a year to maintain gloss and prevent fading.
Buff with a microfibre cloth for extra shine and protection.

Troubleshooting Common Issues With uPVC Window Frames

Dealing with Discoloration and Stubborn Marks

If your white uPVC frames appear yellow or grey despite cleaning, try these tips:

Bicarbonate of soda paste can lift persistent stains.
Specialist uPVC cleaners are available for more stubborn issues but always test on an inconspicuous area first.
Avoid painting uPVC unless using dedicated uPVC paint--this can void warranties or cause poor results.

Preventing Mold and Damp

Ensure adequate ventilation to reduce condensation.
Regular cleaning removes organic matter and inhibits mold growth on frames and seals.
If you notice black marks, clean with a vinegar-water solution, then dry thoroughly.

Shallow scratches can sometimes be polished out with specialized uPVC polish.
Deeper gouges may require professional repair or replacement of affected components.
