Cleaning a Brita pitcher: remove the filter and handwash the lid
Handwash Brita pitcher bodies, lids and reservoirs with mild detergent after removing the filter. Rinse well; avoid dishwashers and abrasive cleaners.
Brita's official US support instructs owners to periodically handwash the pitcher, lid and reservoir with mild detergent while setting the filter aside. Reassemble the parts correctly, and consult the filter-specific setup instructions after replacement.
