To buy: $17 (was $24); amazon.com. The fume-free cleaner is designed to eliminate gunk and stains without tough scrubbing or wiping down. Once the formula has time to work its magic (most users leave it on overnight), simply run some water over your shower or tub to watch the grime go down the drain. You can apply it to nearly any bathroom surface that needs cleaning: shower tile, bathtub basins, fixtures, doors, and even shower curtains. And since it comes with a spray nozzle and hose, it’s easy to reach nooks and crannies that may need some attention. Tons of shoppers use it beyond the shower, too, and rave about its versatility when it comes to cleaning every surface of their bathroom—and even their kitchens. Shoppers with back pain also love its no-fuss application and cleaning power. “Within minutes, all of the built-up dirt and grime began to melt away,” another reviewer wrote. “I left it on overnight, and when I got up this morning, it did not look like the same tub and shower. This product is a godsend, especially for old folks like us who have difficulty getting down on our hands and knees and scrubbing.” If you’re ready to speed up your cleaning routine, it’s a great time to try the popular cleaner. The time-saver is marked down to $17 right now, so be sure to snag a bottle or two now before the price goes back up.
