Only two strings away from an attitude problem.
For soap scum, I mix hydrogen peroxide with baking soda and then use a plastic scrubby (like a shower poof) to scrub. If you have years of build-up, you might need to go with a chemical solution to get rid of it the first time, but this is what I've been doing for years. It's good for removing hair color from grout, too.
