What will clean soap scum and hard water deposits from a glass shower door in a marble shower?

Question

Because of the marble floor, I cannot use any acids. I've triedd using a steam cleaner and it helped some but the bottom of the door is still covered with buildup. Please help!

Answer 1

Try vinegar.  Spray it on and scrub with a toothbrush or something.  Vinegar is good for cleaning water deposits.  If you can, let the vinegar sit for a bit to loosen deposits.

Answer 2

A Magic Clean Eraser.
