Cleaning Soap Scum on Shower Doors

When our home was new, the instructions for the tub and shower said to apply automotive wax to the sides and glass doors, but not to the bottoms, of the shower and tub, to help keep soap scum from forming. It could probably be done after the glass is cleaned well. I didn't do it of course, and now use generic 'Soft Scrub' and a nylon kitchen scrubber to clean the shower doors every week or two.

Try Magic Eraser (or generic equivalent). Once clean, my grandmother uses a squeegie once a day to keep it from building up again.

Best thing I know is vinegar and baking soda. I use this for most of my cleaning. No chemicals so is good for me and the environment.

My mom kept a small squeegee in the tub for this. It takes almost no time at all to quickly run it over the the doors.
