A new exhaust fan changes the bathroom environment and drying pattern. Keep that change in the maintenance record when investigating haze or deposits.
Note when the fan was installed and inspect the glass after compatible cleaning. Do not diagnose a coating from a steamy pane or infer airflow solely from the fan’s label.
Faster drying can change where visible residue remains without identifying a product defect. An exhaust fan is also not an anti-fog coating.
The useful record separates room conditions, cleaning and treatment history. Continue the approved glass routine and provide those details to support if a persistent surface change remains after cleaning.
