Scrub the rubber splash guard occasionally with a long brush and hot soapy water.
Never pour oil or grease into the disposer. Instead, collect fats in a container and then throw the container into the dustbin.
Don’t try to grind large amounts of food at one time.
Run water down the drain for several seconds after grinding is complete, to flush waste and keep debris from settling.
Save and grind used lemons and other citrus fruit peels to freshen up and disinfect the disposer naturally.
