Pure Water Window Cleaning for Second-Storey Windows
Cleaning upstairs windows shouldn't mean a balancing act on a shaky ladder. Here's the modern, professional standard — and the science that makes it work.
The modern professional standard for high windows is Water-Fed Pole (WFP) technology — high-reach cleaning from the safety of the ground, using purified water to achieve a finish a traditional squeegee simply can't match.
The science of pure water
Most people assume water is just water. In fact, tap water is loaded with minerals — calcium, magnesium and sodium. When it evaporates off the glass, those minerals stay behind as the white spots that plague DIY cleaning. Our systems remove them in three stages:
- Carbon filtration — strips the chlorine that can damage specialised seals.
- Reverse osmosis (RO) — a high-pressure membrane that strips around 98% of impurities.
- Deionisation (DI) — a final resin polish that brings the water to 0 ppm (parts per million).
At 0 ppm, water becomes a powerful solvent. It aggressively attracts and lifts dirt from the glass — no harsh chemicals required — then dries to nothing, leaving a spotless finish.
Carbon fibre vs. the elements
A common DIY mistake is reaching for a heavy fibreglass or aluminium pole. At 25 feet, those poles whip and flex, making it impossible to hold the brush flat against the glass. We use ultra-light, high-modulus carbon fibre instead — and that rigidity changes everything:
- Micro-adjustments — precise control over the brush angle.
- Consistent pressure — every square inch of glass is properly agitated.
- Greater reach — stable water-fed pole systems help clean hard-to-reach glazing; Remarkable assesses access for work generally up to three storeys.
The frame-first technique
The most common cause of streaks isn't the glass — it's the frame. Dirt hides in the top seals and corners, so if you clean the glass first, dirty water drips down over it as everything dries. The professional workflow flips the order:
- 1 The frame flush. Scrub and rinse the top and side frames thoroughly first.
- 2 The glass agitation. An overlapping M or S pattern suspends the dirt in the water.
- 3 The final rinse. Holding the brush two inches off the glass, a waterfall rinse flushes everything away.
DIY kit vs. Remarkable
A consumer DIY kit
- Water purity compromised with a basic DI filter
- Gravity-fed cleaning at low pressure
- Cheap bristles risk scratching the glass
- Multiple passes required
Remarkable Window Cleaning
- Continuous RO/DI — purity guaranteed at 0 ppm
- Pump-driven, high-flow agitation
- Soft, dual-trim monofilament brushes
- Faster, more time-efficient results
If your windows haven't been cleaned in over a year, the first pure-water clean can look hazy — that's the water pulling deeply embedded surfactants out of the seals. We deep-clean the frames so the second rinse comes up crystal clear.
Carbon fibre is a conductor. Trained teams are taught to spot overhead power lines a homeowner might miss while looking up. Staying on the ground beats a ladder — but professional awareness is the real safety feature.
