Despite what chapter says, do not mix vinegar (an acid) with baking soda (a base), because all you'll end up with is salty water.

[Magpie_Bridge]

it's usually you mix equal parts dishwashing liquid and heated (not boiling) distilled white vinegar to break down heavy soap scum, body grime, and mineral deposits on shower walls and tubs. the baking soda is the post soak abrasive for a shiny finish.
unless you have some sort of natural stone in your shower, you gotta replace the vinegar with a stone-safe bathroom cleaner (learned the hard way).
