Method + problem playbook
Authority graph: primary / compatible method + problem playbook.
primary fit for fingerprints and smudges using glass cleaning.
Hands transfer oils, lotions, food residue, sanitizer film, and fine dust. Glossy surfaces show it first; textured or matte surfaces hold it longer. Frequent touchpoints in rentals, offices, hospitality rooms, and family kitchens need a maintenance rhythm, not occasional spot chasing.
Ranked for fingerprints on glass.
These products are selected based on what actually works for the problem, surface, and cleaning goal.

Glass cleaning is connected to fingerprints and smudges 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.
