What can I do about Cloudy/stained sliding glass doors?

Try using white vinegar and water 50/50 ,spray on the glass and wipe off with newspaper.

Dampen a used fabric softener sheet with a few drops of water and wipe the glass down. Also works to remove soap scum off shower doors, polish faucets, chrome cleaner, and dusting. Add a little vinegar to remove mineral deposits off shower doors.

Ok thank you I'll try that too!

I also use a vinegar spray! Works like magic!

Thanks for the vote of confidence, I'll give it a try!

Apparently shampoo works well to clean shower doors so guess it can be used on glass too

Hometalk has a great guide on cleaning foggy windows here: https://www.hometalk.com/diy/clean/windows/how-to-clean-cloudy-glass-windows-44456953

Hi Jana: I'd try using a magic eraser dipped in a 50/50 vinegar/water mix. Just be gentle and it should work. If it's on both sides of the door, go one way, like back and forth on the inside and on the outside, go up and down. Then, when you see any streaking, you'll know which side it's on. Same way with washing windows :)

Good luck
