My daughter cleaned our new glass storm door with a TSP solution instead of glass cleaner. Then she allowed it to dry instead of wiping it dry. Now there appears to be an irridescent film that I have been unable to remove with glass cleaner. Any suggestions?

- Removing film from glass
Concentrated TSP, or TSP allowed to dry on glass can cause etching. If that has happened the damage may be irreversible. Hydrofluoric and phosphoric acids are better known etching agents, but trisodium phosphate, while slower, can also severely damage glass. If you view the glass surface with a magnifying glass you will see if the surface has etched, or if it is indeed a film.
I've had good results removing the film using the suggestion on a TSP package......
Prepare a fresh weak solution of TSP and clean rags to clean the glass.......
Re-wash the glass with fresh rags and Clean water.........
Rinse the glass again with clean water and immediately BUFF the glass dry using soft paper toweling.......
