Soft microfiber cloths or sponges
Mild dish soap or uPVC cleaner
Warm water
Non-abrasive cream cleaner (for stubborn stains)
Vacuum or soft brush to remove dust
Old toothbrush (for tricky corners)
Dry cloth for polishing

Start by vacuuming or brushing loose dirt from the window frames. This step prevents scratches during cleaning. Pay attention to window tracks and drainage holes, as build-up can affect window operation.

3. Prepare a Gentle Cleaning Solution

Mix warm water with a few drops of mild dish soap.
Avoid harsh chemicals or solvents, as these can damage the uPVC finish.

Never use bleach, whitening agents, or scouring pads, as these may scratch or discolor your window frames.

4. Wipe Down the Frames

Dip your microfiber cloth in the soapy water.
Gently wipe all surfaces of the window frames, including the edges and corners.
Use the old toothbrush for tight spaces and stubborn grime.
Rinse the cloth regularly in clean water.

Tip: For external uPVC window frames, consider cleaning on a cloudy day to prevent water spots from the sun.

5. Tackle Tough Stains and Marks

Apply a non-abrasive cream cleaner directly to any marks or stains.
Let it sit for a few minutes.
Gently scrub using circular motions with a soft cloth.
Wipe away any residue with clean water.

*Avoid abrasive sponges, wire wool, or harsh chemicals* if you want to keep uPVC windows gleaming without causing damage.

6. Dry and Polish for a Gleaming Finish

Use a dry, lint-free cloth to polish the window frames after cleaning.
This prevents streaks and keeps the finish bright.
