This is more a practical convenience and cross-contamination consideration than a strict hygiene requirement.
Cross-contamination of strong cleaning products is the main concern
A cloth or brush previously used with a strong-smelling household cleaner (a heavy-duty kitchen degreaser, for instance) could transfer residual scent or chemical residue to glassware or dispensing equipment if reused without thorough washing in between — dedicated tools avoid this risk entirely.
Dedicated tools simplify keeping track of what’s clean
Beyond the cross-contamination concern, having tools specifically set aside for bar equipment makes it easier to know they’re appropriately clean and ready for that specific use, rather than uncertain about what they were last used for.
Thorough washing between uses is the alternative to dedicating tools
For anyone who prefers not to maintain separate tools, thoroughly washing a shared cloth or brush between different uses addresses the cross-contamination concern without needing fully dedicated equipment.
What to do in practice
Dedicate specific cloths and brushes to bar equipment for convenience and to avoid cross-contamination risk, or thoroughly wash shared tools between different uses if maintaining separate ones isn’t practical.
What we would not do
Suggest sharing cleaning tools poses a serious hygiene risk on its own — it’s a practical cross-contamination consideration, addressable either by dedicating tools or washing thoroughly between uses.
