How to Clean Windows in London: A Smart Seasonal Guide for City Living
Spring has finally arrived in London—and with it, the first proper sunshine in months. As the light streams in, so too does the realisation your windows have spent the winter quietly collecting dust, pollution, and streaks which are hard to ignore.
If you’re wondering how to clean windows in London effectively—whether you’re doing it yourself or hiring help—you’re in the right place.
Urban living brings specific challenges, and this guide is packed with practical solutions, professional insight, and a few tried-and-tested products we genuinely rate (all easily available on Amazon).
Why Cleaning Windows in London Needs a Bit More Effort
Living in the capital means dealing with higher levels of pollution, road dust, and construction debris. All of this clings to your windows—inside and out—making them look dull and blocking precious natural light. In central and high-traffic areas grime builds up fast.
To stay ahead of the mess, we recommend cleaning your windows every 6 weeks to 2 months. It may sound frequent, but you’ll see and feel the difference instantly each time.
Inside vs Outside: Know the Difference
Interior Windows
Marks from hands, pets, condensation or cooking are more noticeable. Fortunately, cleaning the inside of your windows is straightforward, and with the right tools, it’s quick and satisfying.
Exterior Windows
The outside is a different story. It’s where the real grime gathers—thanks to diesel fumes, city dust, and unpredictable weather. Add in awkward access (especially in period homes, townhouses or upper-storey flats) and it’s usually safer and more time efficient to call in professionals.
Best Tools for Cleaning Windows at Home
If you’re tackling the insides yourself, invest in tools that make the job easier, faster and more effective. We recommend:
Method Glass Cleaner Spray – A natural, ammonia-free formula with a minty fresh scent. Great on mirrors too.
E-Cloth Window Cleaning Pack – Microfibre cloths that lift dirt using just water—perfect for quick, streak-free cleaning.
Kärcher WV1 Window Vac – A rechargeable vacuum which removes moisture from glass without leaving lines.
Unger Pro Window Cleaning Kit – Ideal for those who wanting a pro finish.
Make Your Own Window Cleaning Solution
Prefer to mix your own natural products? Combine equal parts white vinegar and water, and add a splash of rubbing alcohol for added shine. Pour into a spray bottle and you have an eco-friendly, effective cleaner in seconds.
How to Clean Inside Windows Like a Pro
Dust first – Use a soft cloth or brush to sweep away cobwebs and particles, especially from the corners and frames.
Spray top to bottom – Apply your cleaner in vertical strokes.
Squeegee in an S-shape – Start from the top and glide across the glass, wiping the blade between passes.
Buff the edges – Use a dry microfibre cloth to soak up any leftover drips.
Don’t forget the frames - Wipe down window sills and frames to remove built-up dust, cobwebs and any drips to finish.
For sticky fingerprints or dried-on mess, let the cleaning product sit briefly. You can also try a dab of bicarbonate of soda or toothpaste (non-gel) for gentle scrubbing.
Cleaning Outside Windows in London
If your windows are accessible and you’re up for the challenge, the Unger Pro Window Cleaning Kit mentioned above includes a Telescopic Pole. Just be careful not to lean out of windows — if you’re in any way unsure about how safely you can do this, back off.
To be honest, we recommend booking a professional to handle the outside - and while they’re at it they could easily do the insides too. They’ll have the proper kit (and insurance) to deal with height and awkward angles. It’s one of those jobs best left to those who do it daily.
Final pro tip – Before the window cleaners arrive, move your car from directly outside the house. It avoids accidental splashes or, heaven forbid, a flying bucket incident.
Why It’s Worth Doing
Clean windows lift the entire feel of a home. Rooms appear bigger, brighter, airier, and more welcoming.
For those working from home or managing hectic households, it’s a small routine which adds daily calm.
Whether you take it on yourself or leave it to us to arrange for you, freshly cleaned windows are uplifting for you and your family, and a reset well worth making.
