Thank you for your question. The aerator for the Delta B3596LF-SS faucet can be removed to be cleaned. To remove, unscrew the aerator from the spout, counterclockwise, by hand. To clean, soak the aerator in a solution of 50% white vinegar and 50% water mix. This can be soaked for an hour or even overnight.
