Pure water window cleaning uses advanced filtration to strip minerals and contaminants from the water — so when it dries, there's no residue left behind. No chemicals, no detergents, just clean glass. It's one of the methods we use for exterior windows on homes and businesses across the Gold Coast, and it's particularly useful for high or hard-to-reach glass where traditional methods aren't practical.
Gold Coast tap water is full of minerals — particularly calcium and lime. That's what leaves those white spots on your shower screen and streaks on your windows when you try to clean them yourself. When regular water dries on glass, those minerals stay behind.
Pure water has all of that stripped out through de-ionisation — a step above reverse osmosis that removes contaminants down to zero parts per million. Here's where it gets interesting: when water is purified to that level, it becomes a charged particle. Think back to high school chemistry — it has a positive and negative end, which means it actively tries to pull everything it touches back into itself.
That makes it a surprisingly aggressive cleaning agent. It doesn't just rinse dirt off the glass — it draws contaminants into the water itself. The same property that makes it effective for cleaning is why you wouldn't want to drink it consistently — over time, it would leach calcium from your teeth.
It dries clean without squeegeeing, which makes it ideal for exterior glass we're cleaning from the ground with water-fed poles. It's a tool in the toolbox — not better or worse than traditional methods, just different. We use whatever gets the best result for your specific situation.
Pure water shines on exterior glass — especially upper floors, hard-to-reach windows, and anywhere we're using water-fed poles from the ground. It's gentle on delicate coatings and solar panels, and there's no chemical runoff to worry about around gardens or painted surfaces.
For interior glass or windows with heavy oil and grease contamination, traditional squeegee methods often work better. We'll use whatever makes sense for your property — sometimes that's pure water, sometimes it's not, sometimes it's both.
Upper floor exteriors — Water-fed poles reach up to 5 storeys from the ground without ladders
Hard-to-reach windows — Above garages, awnings, extensions, and awkward access points
Solar panels — Manufacturer-approved method that won't void warranties or damage coatings
Pool fencing and balustrades — Great for maintenance cleans, keeping water spots at bay
Properties with gardens below — No chemical runoff to worry about on plants or lawn

Neither is better or worse — both leave crystal clear glass when done right. Pure water dries spot-free without squeegeeing since there's no minerals to leave residue, but it can struggle with oils and some stubborn contaminants. It's also safer for us in most situations since we're working from the ground, though there are times we can't use it — like around power lines. We pick the right method for the job.
Yes. Pure water is the manufacturer-approved method for cleaning solar panels — no chemicals to damage coatings or void warranties. We use the same system for both windows and panels.
More than bucket-and-squeegee, but not as much as you'd think. The filtration and deionising media has a finite life, so it costs us money every time we use it — which means we're not wasting it. We use enough to get a quality result and no more. The trade-off in speed and safety more than makes up for the increased water usage.
