The bottle, cap, spout cap and tether can be cleaned in the top rack of the dishwasher or by hand with warm, soapy water. Remove the cap, spout cap, and tether from the bottle before washing.
For a deeper cleaning, add a drop of mild soap or tablespoon of bleach to a clean glass jar filled with water. Drop the cap, spout cap, and tether into the solution, and tightly close the jar’s lid. Shake the mixture around for 30 seconds, and then let the parts soak for about 15 minutes. Rinse and shake dry.
