Thank you for your question. The aerator of the Delta Pull-Down 19962Z-SD-DST faucet removes from the end of the wand assembly, using the provided wrench/tool RP90248. Then you can soak the entire aerator in a 50/50 mixture of white vinegar and tap water for up to 2 hours at a time for cleaning. Rinse with warm water and reinstall it in the end of the wand.
