Hydrapak Bottle Bright

Hydrapak Bottle Bright is a pack of cleaning tablets that fizz away in warm water to freshen water bottles, soft flasks and hydration bladders without scrubbing. Drop one in, walk away, and come back to a cleaner bottle without any scrubbing.

It is for runners whose bottles, mugs and reservoirs have picked up coffee or tea stains and need more than a rinse. The tablet does the work while the bottle soaks, then you just empty it and rinse. Hydrapak makes them in the USA from plant- and mineral-based ingredients that are readily biodegradable, and says they leave no chemical aftertaste. Use one tablet per litre of warm water and let it stand for 15 to 30 minutes.

For stubborn corners and long drink tubes, pair it with the Flask Cleaning Kit or the Gear Cleaning Kit. Brushes handle the scrubbing, and Bottle Bright takes care of the soak.
