Garbage disposal emits a persistent bad odor even after running

Safety first: Turn OFF power before cleaning inside the disposal.

• Step 1 – Clean splash guard: Remove the rubber splash guard (if removable) and scrub both sides with hot soapy water and a brush. This area often traps odor-causing residue.
• Step 2 – Clean grinding chamber: Pour a mixture of 1/2 cup baking soda followed by 1 cup white vinegar into the disposal. Let it foam for 5–10 minutes, then flush with hot water.
• Step 3 – Deodorize with ice and citrus: With cold water running, feed a tray of ice cubes and a few small pieces of lemon or orange peel into the disposal while running. This helps scour the grind ring.
• Step 4 – Check drain trap: If odors persist, clean the P-trap under the sink, as sludge there can cause smells to back up through the disposal.

Warning: Do not use bleach or harsh chemicals regularly; they can damage rubber components and metal surfaces.
