Method + problem playbook
Authority graph: primary / preferred method + problem playbook.
primary fit for cloudy glass using glass cleaning.
Soap, minerals, humidity, product residue, hard water, and aggressive cleaning history all interact on glass. Coated shower glass is especially sensitive because the wrong chemistry can damage the surface while the original film remains. Recurrence timeline: cloudiness that returns at dry-down points to film; cloudiness that rebuilds over days points to soap/mineral recurrence; cloudiness that never changes after safe lanes is likely etch, coating failure, or permanent wear. Humidity, hard water, soap choice, squeegee habits, and prior acid or abrasive history all determine whether cloudy glass is a removable cycle or delayed surface damage.

Glass cleaning is connected to cloudy glass in the graph because it can address that problem type in the right context. Surface compatibility still determines whether it is actually appropriate.
This playbook usually fails when the visible problem is misidentified, the surface cannot tolerate the method safely, or the finish step leaves behind residue or unevenness.
No. A method-problem relationship does not automatically mean every surface is a safe fit. The surface layer still controls the risk profile.
