However, to ensure your uPVC windows look their best and last for years, regular cleaning is essential. Whether you're a homeowner, property manager, or cleaning enthusiast, our expert guide provides comprehensive steps, tips, and the best products for keeping your uPVC window frames spotless and in top condition.

Why Clean uPVC Window Frames?

• Enhances Appearance: Clean windows and frames boost your home's kerb appeal.
• Maintains Functionality: Dirt and grime can affect opening, closing, and locking mechanisms.

How Often Should You Clean uPVC Window Frames?

The frequency of cleaning your uPVC frames depends on your location and environmental factors. Experts recommend a thorough clean every three to six months. However, homes in coastal areas, near busy roads, or in regions with high pollen counts may need more frequent attention.

Preparing for the Cleaning Process

Gather Your Supplies

• Mild detergent (washing-up liquid or gentle uPVC cleaner)
• Warm water
• Soft cloths or microfiber cloths
• Soft-bristled brush or old toothbrush
• Sponge
• Bucket
• Non-abrasive spray bottle (for stubborn spots)
• White vinegar (for tackling stains)
• Baking soda (for odour and stain removal)
• Vacuum with soft brush attachment
• Optional: Commercial uPVC cream cleaner
• Gloves (to protect your hands)

Avoid abrasive materials such as steel wool, scouring pads, or harsh chemicals like bleach, as these can scratch and discolour your uPVC window frames.

Step-by-Step Guide to Cleaning uPVC Window Frames

1. Remove Loose Dirt & Dust

• Begin by opening windows and dusting around the frames and sills with a soft brush.
• Use a vacuum with a soft brush attachment to remove loose debris from corners, tracks, and hinges.

2. Wash with Mild Detergent Solution

• Mix a small amount of mild detergent in warm water.
• Dip a soft cloth or sponge into the water, wring it out, and gently wipe down the uPVC window frame.
• For tight spots or stubborn dirt, use an old toothbrush or soft brush.

Tip: Work from top to bottom to avoid letting dirty water drip onto already clean areas.

3. Tackle Stains and Yellowing

• For persistent stains, make a paste of baking soda and water. Apply the paste to the stain, let it sit for a few minutes, then gently scrub with a soft brush.
• Alternatively, dilute white vinegar with water (50/50), apply to tough marks, and wipe off with a clean cloth.
• Rinse the area with clean water to remove any residue.

4. Clean the Window Seals & Hinges

• Use a soft cloth with mild detergent to wipe down the rubber seals and gaskets.
• Avoid using strong solvents as they can weaken or degrade the seals.

• Lubricate hinges and locks lightly with a silicone-based spray to maintain smooth operation.

5. Rinse and Dry Thoroughly

• Wipe down the entire uPVC frame with a clean, damp cloth to remove detergent and cleaning residues.
• Dry the frames with a soft, dry microfiber cloth to prevent water spots or streaks.
• Allow all components to air-dry fully before closing the windows.
