I used TSP to clean windows and replace the glazing.

try bar keepers friend it has a mild abrasive in it. I use on my shower doors. What a viking cleaning windows while ur in pain.

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.

What is tsp?

TriSodiumPhosphate

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

Soft scrub...it works.

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

Thanks William! I agree with you regarding the use of toothpaste. Yes, it really works in removal of stains and is an easy process to follow.

There is a way to remove TSP and bleach streak stains dryed on windows for awhile...

I used the recommended advice from Momentumjanitorial.......

The use of toothpaste removed the dryed streak stains... Thank God!!!!

It was very easy to do and a million dollar advice....Thank you so much!!!!

Here's a post that might help https://chascrazycreations.com/eco-friendly-window-and-mirror-cleaning/

I'm going through this right now. Pressure washed the house with TSP my guys weren't rinsing Windows behind them as they went. Etched $40,000 worth of windows! The solution w e i m a n glass cooktop cleaner and polish. Little circular motions everything's gone! Good luck

I agree with William's suggestion of non-abrasive toothpaste. I wouldn't use TSP unless very, very diluted as it could etch the glass and make matters worse for you.

First, take an equal amount of vinegar and water and mix them together in a spray bottle. White distilled vinegar will work best for this. Then, spray the solution on your windows and let it sit for around two to three minutes. Lastly, use a gentle cloth to wipe away the cleaning solution and avoid any streaks.

Try using vinegar! Then put a cowl over window to stop direct external drip.

Hello PM, hope this helps you. TSP can etch glass and mirrors. You can try to steam this clean. but there is no way to repair the damage. If the glass is now cloudy because of TSP, you can attempt to remove the cloudiness using vinegar. Depending on the thickness of the glass and the amount of time the TSP sat on the glass, the cloudiness may only lighten, not completely disappear.
