Cleaning a cocktail shaker is simple.
After each use, disassemble the cocktail shaker and rinse it with warm water to remove any residue. Use a brush or sponge to gently scrub the interior and exterior of the shaker. If there are stubborn stains, you can create a mixture of warm water and mild dish soap to clean it thoroughly. Rinse the shaker again with warm water and dry it with a clean towel or let it air dry before reassembling it for storage.
