Black Spots Appearing on Bathroom Mirror — Rotterdam, Zuid-Holland
Dark spots or blotchy edges spreading across a bathroom mirror indicate desilvering — the reflective silver or aluminum coating on the back of the glass is breaking down from prolonged moisture exposure. Bathrooms without adequate ventilation allow steam from showers to condense on the mirror surface, and water that seeps behind the frame or clips slowly corrodes the metallic backing from the edges inward. Once desilvering starts, it is irreversible: no cleaner, paint, or touch-up product can restore the reflective layer. The mirror needs to be replaced. A handyman can remove the deteriorating mirror safely (avoiding the risk of shattering a large sheet of glass bonded with construction adhesive), prep the wall surface, and install a properly sealed replacement mirror with anti-moisture backing or a framed medicine-cabinet style mount that allows airflow behind the glass.
