How to Clean uPVC Window Frames: Step-by-Step Guide

1. Remove Loose Dust and Debris

Begin by opening the windows and using a vacuum cleaner with a brush attachment to remove all loose dust, dirt, cobwebs, and insect debris from the frames, hinges, and sills. This crucial step ensures that dirt isn't smeared around during washing.

2. Prepare Your Cleaning Solution

Fill a bucket with warm water and add a splash of mild dishwashing liquid or detergent. Avoid using strong chemical cleaners, ammonia, or bleach, as these can tarnish or discolor the uPVC surface.

3. Wipe Down the uPVC Frames

Using a soft cloth or sponge, gently clean the uPVC window frame from top to bottom. Pay extra attention to corners and joints where grime often accumulates.

• Never use abrasive pads or steel wool as they can scratch uPVC surfaces.
• For awkward spots, use an old toothbrush dipped in soapy water.
• Always wring out excess water to avoid drips and streaks.

4. Tackle Stubborn Stains

If simple soapy water isn't enough, try one of these safe methods:

• Baking Soda Paste: Mix baking soda and water into a thick paste. Apply to stains, let sit for 5-10 minutes, then scrub gently with a soft brush or sponge and rinse off.
• White Vinegar: Dilute vinegar with equal parts water, spray onto the stain, let it sit, then wipe clean.
• Specialist uPVC Cleaners: Available at hardware stores, these formulas are specially designed for deep cleaning window frames without causing damage.

*Always spot test any cleaning product or homemade solution on an inconspicuous area to check for adverse reactions.*

5. Wipe Off Excess Moisture

Once your uPVC frames are clean, use a dry microfiber cloth to remove any remaining water. This prevents streaks and water spots and keeps the windows sparkling.

6. Clean Window Tracks and Seals

Don't overlook the window tracks and seals! Use a vacuum for loose debris and then clean with a damp cloth. To prevent rubber seals from cracking, you can occasionally treat them with a silicone-based lubricant.
