Why We Test Your Water With a Digital TDS Meter Before Every Job
Total Dissolved Solids (TDS) measure minerals, salts, and metals in water. When tap water evaporates on warm glass, those minerals stay behind as white spots.
(Leaves mineral spots & streaks)
(100% pure spot-free evaporation)
The Cape Clear Standard: Your lead technician dips a digital meter into our filtered line in front of you. If it doesn't read 000 ppm, we don't start.

How Much Eskom Savings Are Salt & Dust Stealing From Your Solar Panels?
In Cape Town, sea salt mist, red summer clay dust, and bird droppings bake onto glass PV modules. Because panels are wired in strings, shading or crust on even 15% of a panel drags down the entire string's MPPT output.
Warranty Rule: Never let anyone use high-pressure washers, borehole water, or dish soap on solar panels. We use 000 ppm de-ionised water and a soft solar-certified brush.

How much does window cleaning cost in Cape Town in 2026?
Standard ground-floor window panes cost R35 per pane (exterior only) or R55 per pane (interior + exterior + sills). Upper-storey panes cleaned safely from the ground with our carbon-fibre pure-water poles range from R55 to R85 per pane. Frameless glass balustrades are R25–R32 per panel, sliding/stacking doors are R48–R75 per panel, and rooftop solar panels are R45 per panel when added to a window clean. Our minimum call-out fee is R890 (exterior) or R1,050 (interior + exterior).
Why doesn't your pure water leave water spots when it dries in the sun?
Water spots are caused by dissolved minerals (calcium, magnesium, sodium) left behind when tap water evaporates. Our De-Ionising (DI) resin vessels strip Cape Town municipal water from ~60 ppm down to 000 ppm pure H₂O. Because there are zero dissolved solids in the water, it dries 100% invisible and streak-free — even in direct summer sunlight.
What if it rains or the South-Easter blows right after you clean my windows?
First, rain itself is mostly pure water — windows only spot after rain when rain mixes with old soap residue or dust already sitting on the glass. Because we use zero soap on exteriors, normal rain runs straight off. Second, if you are on any Coastal Salt Club recurring plan (Quarterly, Bi-Monthly, or Monthly) and a freak mud-rain or gale hits within 7 days, let us know on WhatsApp and we will touch up your ocean-facing exterior panes free of charge.
Do you clean high-rise buildings that need rope access / abseiling?
Yes. Up to 4–5 storeys (15 metres), our own crew cleans from the ground using ultra-rigid high-modulus carbon-fibre poles — which saves body corporates 30–40% over abseiling. For buildings 5 storeys and higher, or architectural glass that cannot be reached from the ground, we dispatch a vetted IRPSA Level 1–3 certified rope-access partner team complete with a site-specific OHS Reg 10 Fall Protection Plan and Safety File on Day 1.
Can you remove white borehole sprinkler stains from glass and balustrades?
Yes. Wellpoint and borehole irrigation water in the Southern Suburbs, Blouberg, and Bellville is rich in calcium carbonate and iron oxide, which bonds to glass ("hard-water staining"). Normal window washing cannot remove it. We offer dedicated chemical-and-micro-polishing restoration to dissolve Stage 1 and Stage 2 mineral buildup before sealing the glass.
