Unplasticized Polyvinyl Chloride (UPVC) is the most popular material for window frames. UPVC is easy to manufacture, long-lasting and relatively easy to maintain.
While it’s resistant to rotting and rusting, UPVC windows can become dirty from build-ups of muck and grime if not properly maintained. Luckily, cleaning UPVC window frames is straightforward, and by following a few simple steps, you can keep your windows looking clean and fresh all year round.
How to clean UPVC window frames
Although you can choose the colour and finish of your UPVC frames, most people opt for white. If you have white UPVC, you should be aware that when it comes to cleaning them, there are certain cleaning products to avoid. Generally, UPVC window frames can be cleaned with a few simple products. Here’s what you’ll need: - A bucket of warm water - Mild washing up liquid or a specialist uPVC cleaner - A soft sponge or microfibre cloth - A soft-bristled brush or old toothbrush (to get to those tricky crevices) - White vinegar (for stubborn stains) -A dry cloth or towel Step-by-step cleaning guide
- Remove the loose surface dirt
Wipe down your window frames with a dry cloth or a soft brush to remove any loose dust or debris.
- Wash the UPVC frames with warm soapy water
It may sound simple, but this is all you need to use if you’re cleaning your windows regularly. Giving your UPVC a quick scrub with a sponge and soapy water is enough to remove light dirt and keep your frames looking nice and bright.
- Scrub all crevices and seals with a brush
Use your soft-bristled brush or toothbrush to scrub the hard-to-get-to corners, seals and joints.
- Use white vinegar and water on stubborn stains
If warm soapy water doesn’t do the trick on tougher marks and stains, mix white vinegar and water (1:1 ratio). Wipe the solution onto the window frames and leave it for a few minutes before wiping off.
- Rinse and dry your window frames
Remove any soapy residue with clean water and then dry the frames with a soft cloth to prevent watermarks.
- Apply polish (optional)
If you want your window frames to shine, use a UPVC cleaner to enhance the finish.
What is a UPVC cleaner?
UPVC cleaners are specially formulated to remove dirt and stains from UPVC window frames and doors. Specialist UPVC cleaners usually come in the form of a cream or paste and can help to remove really stubborn muck without posing a risk to your double glazing or window frames.
What to avoid when cleaning UPVC window frames
Avoid harsh chemicals
Don’t use products that contain bleach, white spirits, methylated spirits, nail varnish remover or any other harsh chemicals. Ignore any old wives tales that recommend such cleaners as this type of product will damage your UPVC frames, window sills and potentially the surrounding paintwork or wallpaper.
Avoid cleaning products that contain dyes
Check your cleaning products thoroughly before using them on your windows. Even harmless dish soap can contain dyes to give them a bright colour. Although they’re fine for their intended purpose, if used on UPVC, they could end up staining your lovely bright frames, which will be very difficult to remedy.
Avoid using rough sponges
A soft cloth is the ideal material for wiping down your windows. If you don’t have one to hand, don’t be tempted to use a scourer or abrasive sponge, as you’ll risk scratching your UPVC frames.
