Soap Scum on Shower Doors

I use a product called Bartenders Friend from Home Depot with a bit of vinegar and a non scratch sponge. Once my shower is clean I wipe it down with a towel after every use. Then once a month I clean the shower and it is a snap because using the towel after every use it picks up most of the soap scum.

The best way to clean shower doors is with used dryer sheets! Just scrub them with the used sheet, and the scum comes right off, and stays off longer, too. Also, it smells great!
