A: Hello! (re)zips are dishwasher safe on the top rack using low heat. For best results, hand wash is recommended. Fill (re)zip halfway with warm water and add a small amount of dish soap. Gently swirl bag to make sure all internal surfaces are cleaned, using a bottle brush if necessary. Rinse thoroughly. Drape over dishrack prongs and prop open to dry. Additional options for drying include placing over a glass or mug, or placing a fabric napkin or washcloth inside to absorb water and dry completely.
