Immediately wash and dry well after use, then store it away from other metals to prevent rust. Wash with care. Do not use abrasive cleansers or steel wool. Do not use chlorine bleach as it may cause rust. When rust spots are found inside the tumbler, add warm water and citric acid in ratio of 10:1, wash with soft sponge after leaving it for 2-3 hours, and rinse well.
