You do have to let it sit for four to five hours (or even overnight), but the results, at least according to reviewers, are worth it. This is another item that’s recommended by our readers (see the review below). You can get a bottle on Amazon for $13.99, or two for $26.99.
Promising review: “After living in my place for a few years, my shower was super gross. I tried to use elbow grease and disinfecting wipes but failed. Then I discovered this product through BuzzFeed. Holy moly, am I glad I tried it. I left it on for 4–5 hours, per the instructions, and every place this gel touched, the mold/mildew disappeared.” —Gracielou Freebush
(You can also use cotton coil and bleach to the same effect — here’s a tutorial — but I’ve done this and, while effective, it’s very fume-y.)
