Removing film from glass

white vinegar.

White vinegar didn't work either. I really scrubbed with it too.

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.......

I had drip marks from tsp etched into my windows which neither vinegar or dilute tsp would remove. I made a paste of powdered glass and vinegar and rubbed it in a circular motion over the marks then rinsed with clean water. This worked very well.
I would definitely test a small inconspicuous area first.
p.s. The glass powder came from a glass grinder I use to make stained glass windows.

I inadvertently left tsp streaks on window glass. I then tried everything under the sun to remove it: vinegar, a light solution of tsp, window cleaners, glass buffing cloths, etc... Nothing worked.

Finally, I was using a white out product to clear the white film that develops on the inside tempered glass pane on a gas fireplace screen and, lo and behold, it worked perfectly.

Hope this info helps someone out.

Any ceramic stove top cleaner will remove the stains. Be careful on the application as the ceramic cleaner will make swirls that you can see in the light. I recommend using an orbital buffer to apply and then applying Rain X afterward.

For TSP stains on glass, I used Glass cook top cleaner. Put some on a paper towel rubbed in small circles then wipe off immediately with wet towel. Stains are gone! Magic!

I have used Hydra Glitter to clean my window glass...

OMG! You saved my brand new windows! We had washed the lanai with TSP and it splashed on the windows. I rinsed them off at the time but didn't notice the stains on the windows until much later. Nothing removed the stains until I used the cooktop cleaner! Took some elbow grease and I used it with a Magic Eraser. When it got a little too dry, I added a little vinegar to the Magic Eraser. I was afraid my windows were ruined. Thank you sooo much!!!

Ceramic cook top cleaner worked in seconds and the window is cleaner than it's ever been. Whoever made that suggestion, thank you!!

Be very cautious whenever applying HF acid to glass. HF acid can react with the tin side of the glass (99.9% of modern glass has a tin side and air side due to the way it is manufactured - search float glass manufacturing for more details - you cannot discern the tin or air side with your eye - you need a high intensity UV light, which casts a gray reflection off the tin side of the glass. HF reacts immediately with the tin, and damages that side of the glass. That damage can often be removed with a cerium oxide based polish - get a good grade - not cheap stuff - but not always. Safer acids are acetic (vinegar) oxalic, phoshporic. Never apply to hot glass, and always rinse, rinse rinse well. Most cook top cleaners have either cerium oxide or diatemaceous earth as their particulates to remove stains. I own a professional window cleaning company and deal with glass stains/damage regularly. We do NOT use TSP. We use professional detergent designed for glass cleaning (not dish soap)
