Pure Water Window Cleaning in Perth
What Is Pure Water Window Cleaning?
Pure water window cleaning, also called water-fed or reach and wash cleaning, uses purified, deionised water pumped through a water-fed pole to clean glass up to six storeys from the ground.
Because the water contains no minerals or detergent, it dries completely spot-free, with no residue, no streaks and no film for new dirt to cling to. It's the standard method on every Coates Window Cleaning exterior clean across Perth.
Why Pure Water Beats Traditional Cleaning
In plain terms, the glass isn't just cleaner on the day, it stays cleaner for longer. Perth's bore water staining and building dust are exactly the problems this method was built for. If you grew up calling it window washing, this is the modern version, and it works better.

Common Questions About Pure Water Cleaning
Yes, purified water is "hungry" water. Stripped of its minerals, it binds to dirt and lifts it off the glass, then rinses and dries spot-free. It's the same reason laboratories use deionised water for cleaning.
Light mineral staining, yes. Heavy, baked-on bore staining sometimes needs specialised treatment, and we'll tell you honestly at the quote stage rather than promise a miracle on the day.
Safer than traditional methods, because no chemicals means nothing to react with tints, coatings or seals. It's the same reason we use it for solar panel cleaning
Genuinely, yes, and not in the vague marketing sense. There's no detergent or chemical in the process at all, just purified water, so nothing goes into your garden beds or down the stormwater drain except water. It's the cleanest method there is, in both senses
Nothing, and that's the whole trick. We take everything out instead, running the water through filters that strip the dissolved minerals until it's completely pure. Pure water grabs dirt on its own and dries without a mark, so there's no detergent, no additives, nothing left on your glass.
Outside first, it carries most of the dirt. Once the exterior is done, anything still showing is on the inside, which makes the interior pass quick and precise. It's how we work, and it's the right order if you're ever doing it yourself.
With traditional detergent methods, avoid direct summer sun, the solution dries before it can be rinsed and leaves streaks. Pure water is far more forgiving, which is one reason we can work right through a Perth day, though early morning is still kindest on the glass in the middle of summer.
