When was the last time you cleaned it? I squeegee my glass door after every shower and it looks like new after a year of use.

A good quality glass cleaner would be a start. Then as mentioned above a squeegee after showering.

Magic Eraser should take all that off.

Thank you for your answers, I was not asking for you to lecture me about when was last time I cleaned my shower door. I work about 50 plus hrs a week, and at 4:30 am my last thing on my mind is to squeegee my shower door. I was asking for real advice!

I like using vinegar to clean hard water stains or even CLR. After you get most of the stains off I recommend adding a glass sealer from http://diamondsealsystems.com/. Although it is kind of expensive, it really helps. This product allows the water to slide right off the glass making it a lot easier to clean. This product will not prevent the glass from staining, but just make it a whole lot easier. Hopefully this advice helps.

Deluxe, thanks for the glass sealer link... and all their other products.

Though like you myhaz I thought using the squeegee would be too much hassle... but I gave it a try n found it only takes maybe a half minute while I am in the shower drip drying myself and greatly reduces cleaning time later. My DH does not squeegee but it still is much, much better. Seven years later I still do it and my shower wall looks great. PS I only do the area that gets wet... of course.... :)

I simply use a softscrub to clean... as someone else suggested Magic erasers really are... magic IMHO! Though have realized they can take a bit of shine off floors or finishes...

Thank you Deluxe Vanity and Kitchen, I will try the product you recommended. I appreciate your help. :)

Once you get it clean, do try the squeegee. It takes 30-60 seconds. (Get a wide one.)

Is barkeepers friend ok to use on glass? Doesn't it scratch the glass?

and gets a picture of the glass, it's smooth as new and no visable scratches that I can see

Google bkf on lime scale and you'll see there are comparisons out there to show you how better it is vs. something like clr and other products.

Bar Keeper's Friend comes in a liquid version. I use it on my glass cooktop -- works great, no scratches.

Thank you, I didn't know that bar keeper's friend has a liquid version.

I use Bon Ami cleanser on *everything*. I use it on my smooth-top cook top, my sinks, faucets, etc. This is actually a polishing powder. It's the can with the little chick and the motto, "Hasn't scratched yet." This is not like Comet or Ajax; they are abrasives and DO scratch surfaces.

I hope you have not ruined your glass with those bristles.

Lime Scale Remover can remove those kinds of stains.
