What Is Pure Water Window Cleaning?
Pure water window cleaning uses a telescopic water-fed pole with 100% purified water. The water passes through DI
(deionised) and/or RO (reverse osmosis) filtration systems to remove minerals that cause spotting and streaks.
This method is now the most popular across the UK for external window cleaning.
- ✔ Reaches windows up to 30–60ft safely from the ground
- ✔ Leaves a streak-free finish once dry
- ✔ No ladders needed, reducing risk and protecting property
- ✔ Cleans window frames and sills at the same time
Homeowners searching for safe, fast pure water window cleaning UK wide often prefer this method
for regular exterior cleans. For price comparisons, see our
UK window cleaning price guides.
What Is Traditional Window Cleaning?
Traditional window cleaning uses a handheld applicator (soapy wash pad) and a rubber squeegee to remove water
manually. It has been the standard method for decades and is still best for internal windows, shopfronts, and areas
requiring precise detailing.
- ✔ Ideal for internal window cleaning
- ✔ Excellent for close-up detailing and shopfront glass
- ✔ Still widely used where access is simple
However, traditional cleaning can cost slightly more on larger homes due to the hand-detailing required.
Pure Water vs Traditional Cleaning: Key Differences
| Feature | Pure Water | Traditional |
|---|---|---|
| Method | Water-fed pole using purified water | Applicator + rubber squeegee |
| Streak-Free Finish | Yes, when dried naturally | Yes, via manual detailing |
| Safety | No ladders needed | Often uses ladders outdoors |
| Speed | Fast, especially for large homes | Slower, requires hand detailing |
| Best For | External windows, high windows, regular rounds | Internal windows, shopfronts, close-up work |
| Cost | Usually cheaper due to speed | £5–£10 more for larger homes |
Which Method Is Cheaper?
In most cases, pure water window cleaning is cheaper for exterior windows because the process is
faster and safer. Traditional window cleaning may cost slightly more on larger homes due to the additional labour
and detailing.

especially high or difficult-to-reach glass.
