Bottle Bright® Cleaning Tablets (12 Tablets)

I was skeptical a tablet could really tackle the mineral buildup in my old bottles, but after one soak they look brand new. I love that they're biodegradable too, which makes tossing the used water easy.

After soaking my grimy water bottles overnight with one of these tablets, the lingering coffee taste finally disappeared completely. The biodegradable formula is a nice bonus since I don't feel bad about washing the residue down the drain.

I've been using these in my 40oz insulated bottle and they got rid of the funky smell that scrubbing never touched. I like that they're biodegradable too, so I don't feel bad tossing one in after a hike.
