Step-by-Step Guide: Cleaning uPVC Window Frames

Ready to restore your window frames to their original brilliance? Follow these steps:

1. Remove Surface Dust and Debris

1. Start dry: Use a soft-bristled brush or dry microfiber cloth to gently sweep away loose dust, cobwebs, or sand. This step prevents scratching the uPVC surface during wet cleaning.

2. Wipe Down with Mild Soap Solution

3. Dip your non-abrasive sponge or microfiber cloth into the soapy water and rung out excess liquid. Wipe the uPVC frames thoroughly, working from top to bottom.

3. Focus on Stains and Stubborn Dirt

3. Apply specialist uPVC cleaner onto stubborn stains or ingrained dirt. Use an old toothbrush to reach tight corners and rub gently to avoid scratching.
4. Baking soda paste: For persistent marks or yellow stains, make a paste with baking soda and a little water. Rub the paste onto the stain with a soft cloth, then rinse thoroughly.

4. Removing Mold and Mildew

4. White vinegar solution: Mix equal parts white vinegar and water in a spray bottle. Spray directly onto moldy spots, leave for 10-15 minutes, then scrub gently with a soft brush or cloth.
5. Rinse with clean water and dry with a towel.

5. Final Rinse and Dry
