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.
