A replacement shower head can change where droplets and residue land. Review exposure before changing the coating-care products.
Record the installation date and ordinary spray pattern. Check whether maintenance of the fitting introduced cleaner residue on the pane. Compare the glass after a known compatible clean.
Changing the cleaner and adding a topper at the same time hides which change affected the result. A new spot pattern alone does not establish coating failure.
The useful routine reflects the new fitting while preserving compatible glass care. Ask for product-specific advice where deposits persist, and keep fitting maintenance separate from glass treatment renewal.
