What is the best way to remove water deposits from a glass-shower

have you tried white vinegar on a soft rag?

CLR or another calcium lime rust remover, once you get it clean be sure to dry the doors with a squeegee and towel to prevent more build up!

I know this is gonna sound strange but I use the blue Lysol gel toilet cleaner. It does a marvelous job as a matter of fact I did it to my shower 2 days ago. We have very hard water so minteral deposits are left on the glass. I thought i would have to replace shower walls but one day out of desperation cuz it looked so bad I tried the Lysol gel. It works so well . Now I only have to do it about every 3 months or so. I would test it on a very small section of your brass framing ( down near the bottom to see if it affects it but I use it on my silver framing and it does not affect it at all. I am so thrilled to have found a solution .....now I dont need to replace the shower walls. Oh , I squirt it on the walls and smear it around to cover , then leave it for 10 to 15 minutes . I then use a little plastic scrunger to go over the walls and then rinse with water . Voila ! lovely clear glass walls. Just one other thing to mention, I use gloves while doing this just to be on the safe side ....there are no fumes that I have been able to detect.

white vinegar and water 50/50 a dab of blue dawn dish soap and a dab of jet dry with a Mr. Clean Magic eraser.Once the initial soap scum is removed, use a daily shower spray and a squeege

CLR cleaner.

Make a paste with Barkeepers Friend. Work in thirds...scrub with teflon side of a scrubby sponge and rinse thoroughly. Its a miracle!

Hair conditioner will work also.

CLR, or Zep calcium lime rust remover, then squeegee or dry the shower after each use to prevent this buildup from happening again.

Use an acid cleaner such as scrubbing bubbles. Spray the glass, wait a few minutes, then lightly scrub with a nylon scrubby. While it is still softened, repeat, then rinse and dry.
