Holds 2.2 gallons.
How to maintain: We recommend emptying your urine bottle often (every day or two) and not leaving urine in the bottle if the toilet is not in use. Urine that is left in the odor can create odor from the build of of uric acid. Emptying the bottle when it is 3/4 full will help prevent overflow of the urine into the base. If you do have build up, we recommend a product called Lemishine. It is a dishwasher cleaner and can be found at most grocery stores, in the dishwashing isle. You can mix with warm water and soak the bottle overnight to clean off any build up and/or staining.
