Equipment needed to clean a UPVC window

UPVC has a thin film that gives it its shine and protects it. Do not use unsuitable products or abrasive sponges for cleaning to avoid damaging this film.

Prepare the following solution:

– Add 1 glass of vinegar to 4 glasses of hot water.

– Put it in a spray bottle.

You will still need to buy a commercial polish to restore the UPVC to its original shine after cleaning.

Good to know: unique UPVC cleaning products are also on the market.

2. Clean your UPVC windows

– Open your UPVC windows wide and vacuum all the grooves and crevices where dust may accumulate. If the suction power is not enough, you can use a blower to rough up the work.

– Spray the vinegar/hot water mixture (20% vinegar to 80% hot water) onto the frame of your UPVC window.

– Leave for at least 2 minutes.

– Wipe with a slightly damp cloth, focusing on the most affected areas.

– Then dry with a dry lint-free cloth to remove any residual traces.

– After this step, if any traces remain, repeat the operation.

Tip: for regular cleaning, you can use baby wipes that are gentle on UPVC.

Caution: if your UPVC windows face north, they are more likely to suffer from moisture. It would help if you, therefore, be extra vigilant.

3. Apply the UPVC polish
