I hope we’re not annoying you with too many green cleaner posts, but when I saw this post at Re-Nest on how to scrub the tub with half a grapefruit and some salt, I had to give it a try. The comments at the original post were divided, with one person proclaiming it “Absurd!” (harsh) and more than one complaining that it was a waste of a grapefruit. Well, I figured one acidic citrus would do as well as another, so I bought a large lemon, halved it, and coupled it with some sea salt to take on my own tub and sink. For the tub, mixed reviews, but I’m starting to suspect it’s just my tub. I’ve written before about how our house is a work in progress — it was previously a rental, and it’s become apparent that someone cleaned the tub with something that removed a lot of the shiny finish. So while my tub smelled amazing after a scrubbing with lemon and salt, it didn’t look a whole lot cleaner to the eye. Our sink, however, has its porcelain finish, and it looks fantastic! Shiny as new! I will caution you that some of the commenters warn against using large-grain salt on an acrylic finish because it could scratch. See the how-to with grapefruit here. — Mary T.
