Big glass is where streaks hide best — invisible until the sun comes through. Here's the simple method to get windows and sliding doors genuinely crystal clear, using nothing but water.
The method, in one sentence:
Wipe the glass with a slightly damp Mini or LITE to lift the dirt, then immediately follow with a completely dry XXL to soak up every drop — working one section at a time, out of direct sunlight.
Step by step guide:
1. Pick your moment. Clean in the shade or earlier in the day. On sun-heated glass, water evaporates before you can wipe it, leaving mineral marks behind.
2. Do the frames and tracks first. Dust and grit from frames falls onto clean glass. A quick wipe of frames, sills and sliding door tracks means you only clean the glass once.
3. Dampen your Mini or LITE. Slightly damp, not dripping — wring it well. Wipe the glass in overlapping "S" strokes from top to bottom to lift dust film, fingerprints and paw prints off the glass, not across it.
4. Finish dry with the XXL. Straight after each section, buff with the completely dry XXL. This is what pulls every last droplet and gives the streak-free finish.
5. Work in sections. On large sliding doors, do one panel-width at a time — wet pass, dry pass, then move on. Never let water dry on its own.
First time cleaning old glass?
If sprays have been used on the glass for years, there's an invisible chemical film built up. Your first clean lifts that old residue, so it may take one extra pass — after that, water alone keeps it perfect. Doing the outside too? Same method; just rinse very dirty exterior glass with plain water first so grit doesn't scratch.
Common Questions
Q1) Do I really not need any window spray?
No spray needed — the microfibre structure lifts grime mechanically, and sprays are actually a major cause of streaks, since they leave a film that shows up in sunlight. Water is the only thing required.
Q2) Why do streaks only show up when the sun hits?
Because streaks are thin layers of residue — spray film, softener buildup or dragged-around water. They're invisible in flat light and obvious in direct light. Follow the wet-then-dry method and there's no residue left to catch the sun.
Q3) Is it safe on tinted windows and glass pool fencing?
Yes — it's ideal for them. Because you're using no chemicals, there's nothing to damage tint film or coated glass. Many customers use theirs on tinted car windows and pool fence panels for exactly that reason.
Q4) My XXL gets heavy on big sliding doors — is that normal?
Yes — that weight is the cloth doing its job. If it saturates before you finish, that's your cue to wring the damp cloth drier, or keep a second dry XXL handy for the final panels.
