Pure-water window cleaning uses purified water and a soft brush on a long carbon-fiber pole — no soap, no squeegee, and no ladders. Because the water has had its minerals stripped out, the glass dries completely spot-free. It's the method we use on every Blitz job.
How it actually works
Normal tap water is full of dissolved minerals — calcium, magnesium, and salts. Those are the exact things that dry into spots and streaks on glass. Pure-water cleaning solves that at the source:
- Tap water is run through a multi-stage filter (carbon, then a deionizing resin) that strips out essentially all the minerals.
- That purified water is fed up a lightweight pole to a soft brush head that agitates and loosens dirt on the glass, frames, and screens.
- The same pure water rinses everything. Because it's "hungry" (mineral-free), it grabs leftover dirt and then dries behind itself with nothing left to form a spot.
Why it beats soap and a squeegee
- No soap film. Soap residue attracts dust and causes the "clean for two days, then hazy" problem. Pure water leaves nothing behind.
- No ladders. The pole reaches second- and third-story windows from the ground — safer for everyone and no ladder feet in your flower beds.
- Frames and screens too. The brush cleans the whole window, not just the glass, so dirt doesn't wash back down onto clean panes.
- No chemicals. Just purified water — safe around kids, pets, and your landscaping.
What to expect on a Blitz job
We brush each window, rinse it with pure water, and move on — most exterior jobs are quick and we work from the ground. Interior glass is cleaned separately by hand for that final touch. You don't need to be home for the exterior; we just need gate access and pets secured.
