Not only will this improve the appearance of your home, but it will also help protect your windows from damage caused by dirt and grime. So grab your cleaning supplies and let’s get started on this fun and rewarding project that will leave your windows looking crystal clean
Why Regular Cleaning of UPVC Windows Is Important
While UPVC windows are designed to be long-lasting and low-maintenance, they still require regular cleaning to keep them looking pristine and working properly. Over time, dirt, grime, mold, and mildew can build up on the frames, glass, and seals. Not only does this look unsightly, but it can also lead to damage if left unchecked.
Regular cleaning keeps the glass clear for better visibility and light transmission. It also prevents the growth of mold and mildew which could spread to window seals and frames. Eventually, this could cause rot, leaks, and drafts. Lastly, washing UPVC windows routinely protects them from UV damage caused by the sun’s rays. A good clean improves longevity.
How Often Should You Clean UPVC Windows?
Experts recommend cleaning UPVC windows at least once every 2-3 months. This helps prevent the buildup of stubborn dirt and debris. For UPVC windows in high-traffic areas or exposed to the elements, monthly cleaning is better.
Wash windows whenever you notice accumulated grime, spots, or environmental stains. It’s easiest to clean UPVC windows before dirt becomes heavily encrusted so aim for frequent light cleaning sessions.
What You’ll Need To Clean UPVC Windows
Cleaning UPVC windows is a simple process that doesn’t require many supplies. Here are the basic items you’ll need:
- A soft sponge or microfiber cloth
- Mild liquid soap or dish detergent
- Water (warm water works best)
- UPVC cream cleaner or window/glass cleaner (optional)
- An old toothbrush for hard to reach areas (optional)
- Squeegee to dry glass
Never use abrasive scouring pads or brushes on UPVC. Avoid solvents, bleach, hydrochloric acid, or other harsh chemicals that could damage the frames.
Step-By-Step Guide To Cleaning UPVC Windows
Follow these steps to properly clean all parts of your UPVC windows:
1. Prepare your window cleaning solution
Mix a few drops of mild liquid soap or dish detergent into a bucket of warm water. If needed, add 1 part vinegar to 4 parts water for extra cleaning power. Alternatively, use a specialized UPVC window cleaning spray.
2. Clean the UPVC window frames and sills
Dip a soft sponge into your cleaning solution and wring it nearly dry. Gently wipe down all UPVC window frames, sills, and window boards with the damp sponge. Rinse regularly in clean water.
Make sure to scrub any dirty spots and wipe away grime around hinges or locks. Use a toothbrush to clean in crevices. Avoid saturating window seals with water.
3. Wash the window panes
Apply the window cleaning solution directly to glass panes with a sponge or soft cloth. Wipe in “S” shaped motions horizontally first, then vertically.
Rinse the sponge frequently to prevent scratching the glass. Pay extra attention to the corners of the panes.
Use a squeegee on the glass starting from the top corner downwards to avoid streaks. Wipe away any pooled water on sills or frames.
4. Inspect and double check seals & rubbers
Closely inspect all window seals and rubbers around the perimeter of the sash after cleaning. Make sure no dirt or moisture remains.
Reapply your window cleaning solution or rub a bit of talcum powder on rubbers to ensure they don’t become fuse to the frame.
5. Leave windows open to dry completely
After washing, open your UPVC windows wide to allow the sills, seals, and frames to dry fully. Ensure no water is trapped anywhere on the window before closing them up.
Tips For Cleaning Tricky UPVC Window Stains
Beyond routine window washing, you may occasionally deal with tough stains on your UPVC windows that require extra elbow grease. Here are some tips for tackling common stubborn window stains:
- Mold & Mildew – Use warm, soapy water or a diluted bleach spray. Avoid abrasives.
- Bird Droppings – Soften with water and gently scrape off. Rinse immediately.
- Tree Sap & Bug Guts – Apply baby oil and let sit before wiping away.
- Construction Dust – Wipe with a microfiber cloth dampened with window cleaner.
- Hard Water Spots – Clean with a 50/50 vinegar and water solution.
For truly difficult stains, seek out specialized UPVC window cleaning products. Always test cleaners on a small area first to check for any damage to the frames.
