Method + problem playbook
Authority graph: primary / preferred method + problem playbook.
primary fit for surface haze using glass cleaning.
Haze develops when thin layers dry unevenly or when a finish is altered. Product stacking, hard water, microfiber saturation, oily aerosols, humidity, and abrasive history all change the diagnosis. Recurrence timeline: haze that returns as soon as the surface dries usually means residue or mineral film; haze that returns after several cleanings often means product stacking; haze that stays fixed through safe test lanes points to delayed finish damage. Improper chemistry loops are common: adding more spray leaves more solids, acid on the wrong surface creates dullness, and polish hides film while building the next haze layer.

Glass cleaning is connected to surface haze 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.
