An odor developing over time is generally a sign that some part of the shaker’s cleaning routine has been incomplete, worth addressing directly rather than masking.
See our existing note on proper shaker cleaning as the baseline
Our note on what cleans a cocktail shaker properly covers the standard routine — an odor developing suggests some part of that routine, or some accessible surface, has been missed rather than the shaker being fundamentally different.
Residue in hard-to-reach areas is the likely source
Devices like Rosenstein & Söhne’s or amara-global’s electric shakers have internal mixing components that can accumulate residue in less obviously accessible spots — disassembling as far as the manufacturer’s instructions allow, rather than only rinsing the main visible chamber, addresses this more thoroughly.
Full drying after cleaning prevents recurrence
Similar to the general principle covered in our decanter and ice mold storage notes, ensuring the shaker is fully dry after cleaning, rather than stored damp, helps prevent the odor from returning between uses.
What to do in practice
Disassemble as far as the manufacturer allows, clean every accessible surface thoroughly rather than just the main visible chamber, and ensure full drying before storage.
What we would not do
Treat an odor as something to mask with a stronger-smelling cleaning product rather than addressing the underlying residue directly through more thorough cleaning.
