Cleaning windows and glass with ozone water: streak‑free workflow

With ozone water you can clean windows and glass efficiently and streak‑free when you apply it in a controlled way and dry immediately. Usage is BPR‑compliant and strictly for surface cleaning (not for consumption or medical purposes).

 

Step‑by‑step workflow (two‑cloth method)

Mist a light spray onto microfiber cloth A or directly onto the glass in small sections. Clean with overlapping passes and dry immediately with cloth B or a squeegee. Work from edges to center and swap cloths in time to avoid buildup.

 

  • Contact areas first: frames, handles, tracks

  • Glass: vertical then horizontal for control

  • Touchscreens/mirrors: prefer cloth application

 

Practical tips for a streak‑free finish

Avoid direct sun and strong drafts. Finish large panes section by section. Replace cloths when damp or soiled. For outdoor panes, rinse sand or salt first to prevent micro‑scratches.

 

Costs and affordability

For only €0.0017 per liter you produce your own cleaning water from tap water.

 

  • ✅ No expensive bottles or logistics

  • ✅ Less plastic and storage

  • ✅ Chemical‑free cleaning

  • ✅ Easy to use

  • After ~1,000 hours or 500,000 liters, inspect electrodes; parts average ~€75 (sometimes not needed after inspection).
