The residue at the bottom of my water bottle is finally gone after just one soak, and I didn't have to scrub at all. The fizzing action really does the heavy lifting, and the smell disappeared without any lingering chemical scent.

The first thing I noticed was how the stains in my gym bottle lifted after just one soak, no scrubbing needed. The odor was completely gone too, which is more than I can say for my old rinse-and-repeat routine.

I’ve had a stubborn coffee-stained thermos sitting in my cabinet for months, and one tablet in warm water took care of it within twenty minutes. The whole bottle smells fresh again, no scrubbing needed. My only regret is not finding these sooner.
