Soap scum, lime scale and calcium from my beveled glass shower door?

Pamela, one of my rentals has a glass shower door. You have 2 problems, one soap scum ( grease) and two (hard water) I take the door off and do this outdoors wearing eye protection and heavy rubber gloves. Place door on an outdoor table or sawhorses. Use Works Toilet Bowl Cleaner (acid) and blue Dawn (degreaser) squirt both products generously on the glass and scrub around with a brush. Let stand awhile. Then scrub some more and rinse. It should all come off! Sparkling!

CLR only on the glass as it will harm other surfaces.

Try a solution or water, vinegar, dish soap, and baking soda - spray and scrub.

If you can remove the shower door fairly easily, lay it flat on the ground, sprinkle with baking soda, and lay a vinegar saturated towel over it for a minimum of 20 minutes. Then using a magic eraser, GENTLY apply pressure and scrub it. If you cannot take it down easily, make a paste out of the baking soda, apply it and then using a spray bottle, spray with vinegar. Let sit few minutes (you don't want it to completely dry out), and then use the magic eraser. I have had to do the second one in the past ad it worked great.

Is it possibly mineral deposits from the water? If so try spraying vinegar and scrubbing with a new kitchen scrubber.

Kaboom has a soap scum cleaner that worked foe me.

If you can take your doors out of the shower, lay them down and try using undiluted baby oil! You can purchase at the $ store! I'd buy at least 2 bottles! You can put it on with a cloth or paper towel, use a good amount! Let it sit for 30 minutes to an hour! Rinse with warm soapy water. I did this in the summer, took the doors outside and used the hose and dish soap! That's worked for me!

if you're unable to take your doors down, just apply the baby oil with cloth and continue as above! Be sure to clean the bottom of shower/tub good, the oil makes it slippery!

After I got my doors cleaned, I used the oil process every time I cleaned, kept the doors clean!

Good Luck and Happy New Year!!

Lots of good responses, I use equal parts of vinegar, cheap bottled lemon juice , and a couple of good squirts of dw liquid in a kitchen scrubby.

Tilex soap scum remover works well too. It may take a few applications for my suggestions, but they do work, and maintain well. Using a squeegee daily afterwards will prevent buildup

Thank you all for your helpful advice! I have a few better options than my original plan to use a sledge hammer...
