How to Clean a Food Processor

A quick rinse of the bowl and S-blade handles the obvious mess, but the parts that actually cause lingering garlic smell, musty odor, or a grinding noise over time are easy to miss: the blade hub spindle at the bottom of the bowl, and the rubber seal around the lid's feed tube.

This applies whether you own a full-size processor like the Cuisinart Custom 14-Cup or Breville Sous Chef 16 Pro, or a mini chopper like the Cuisinart Mini-Prep Plus — the main difference is how far the blade assembly comes apart for a deeper clean.

What actually needs cleaning (it's not just the bowl)

Food works its way past the blade and down into the hub spindle at the bottom of the bowl, where the blade locks onto the motor shaft — this is a common spot for stuck-on starch or fibrous vegetable scraps that a quick rinse never reaches.

The rubber gasket around the lid's feed tube, and the ring where the lid locks onto the bowl, also trap moisture and small food particles. On processors with a wide feed tube, like the Cuisinart Elemental, check the pusher attachment too — it slides into the same tube and collects the same residue.

How often to clean it

Rinse the bowl, lid, and blade right after use, before anything dries on — starchy foods like dough and fibrous vegetables harden fast and are much easier to remove while still damp than after they've dried onto the plastic.

Give the blade hub spindle and lid seal a closer look every week or two with regular use, and immediately after processing something strongly flavored like garlic, onion, or hot peppers, since those odors and oils are what soak into plastic and rubber if left sitting.

Step-by-step: bowl, blade, and discs

1. Unplug the base and remove the bowl, lid, blade, and any discs. 2. Handle the S-blade by its plastic hub, not the edge — it stays sharp even after a single use. 3. Soak the bowl, lid, blade, and discs in warm soapy water for 5-10 minutes to loosen starchy or stuck-on food. 4. Use a soft brush to clean inside the blade hub spindle at the bottom of the bowl and around the lid's feed tube seal, where a sponge alone usually can't reach. 5. Rinse and let everything air-dry fully before reassembling — trapped moisture around the seal is what leads to a musty smell later.

Step-by-step: the base and blade hub shaft

1. Never submerge or rinse the motor base under a faucet — it houses the motor and electrical connections. 2. Wipe the base down with a damp cloth, paying attention to the raised shaft that the bowl's blade hub locks onto, since splatter collects right at that connection point. 3. Dry the shaft fully before locking the bowl back into place — a damp connection point is one of the more common reasons a processor's safety interlock feels sticky or the bowl doesn't seat cleanly.

Getting rid of lingering smell or discoloration

A sour or garlicky smell that survives a normal wash is almost always coming from the blade hub spindle or the lid seal, not the bowl itself — go back and brush both specifically rather than re-washing the parts you already cleaned.

Turmeric, carrots, and other strongly pigmented foods can stain clear plastic bowls. Rubbing a little vegetable oil on the stain before washing, or soaking the bowl in water with a tablespoon of baking soda for 15-20 minutes, lifts most discoloration without scrubbing hard enough to scratch the plastic.
