Before I begin this story, let me show you the bottom of my shower. Don’t look if you’re squeamish. . . . I know, right? Nasty.
It’s been like that since I moved into this apartment and nothing has been able to help it (don’t even ask about the carpet.) I’ve tried a ton of different cleaners on that tub and even let it soak in straight bleach for a few hours: the results were patchy at best.
So I figured if I found a frugal and/or natural cleaner that actually worked on this kind of grime, it would be a great contribution to world cleanliness.
