Bladder staining is generally caused by food coloring used in liquids. This staining does not affect the functionality of the bladder, yet can be difficult to remove. We recommend using a chlorine free, non-toxic, and biodegradable tablet to combat stains and odors.

Occasionally users may notice a plastic taste. To reduce, squeeze lemon juice into the reservoir, fill with water, and place in the freezer. After frozen, remove, thaw, and rinse.
