I used TSP to clean windows and replace the glazing.

by PM
Had an emergency appendectomy before I was able to clean the glass, and now the glass is stained. How can I clean the run stained glass?

    TSP is not to be used any where near glass or mirrors, it will etch it......that will never come off.....

    You could try steam cleaning the glass.

    I would try CLR, you can get it in a spray bottle at the Dollar Tree. I would also pick up a bottle of Awesome Orange, it will clean just about anything. And get one of those soft green abrasive pads.

    Try some white (not gel) toothpaste and a damp cloth. A dab of toothpaste on the cloth and gently rub in a circular motion. Keep the toothpaste moist.

    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.

    Suggestion on a TSP package......

    1. Prepare a fresh weak solution of TSP and clean rags to clean the glass.......

    2. Re-wash the glass with fresh rags and Clean water.........

    3. Rinse the glass again with clean water and immediately BUFF the glass dry using soft paper toweling.......

    There are some good suggestions here on an auto-detailing site that might prove helpful with your window glass. I've used the 0000 steel wool idea (make sure it's 0000 and not a lesser number or you can have scratches) on our car windows and was very pleased with the results.

    Use brasso or a brass polish.

    My dad told me this trick. It removes fine scratches in glass so it should help to polish off your stains

    Julane is correct, the glass, unfortunately, is now etched and there is little remedy at this stage..
