Garbage disposal produces a foul odour even after running with water.

Safety first: Turn off the disposal before cleaning. Do not use harsh chemical drain cleaners inside the unit.

• Clean splash guard: Remove the rubber splash guard (baffle) from the sink opening if it is removable. Scrub both sides with hot soapy water and a brush to remove grease.
• Deodorise chamber: Pour a mixture of baking soda and white vinegar into the disposal. Allow it to foam for 10–15 minutes, then flush with hot water.
• Ice and citrus clean: With cold water running, feed a tray of ice cubes and a few small pieces of lemon or orange peel into the disposal. Briefly run to scour the chamber.
• Clean discharge pipe: If odour persists, remove and clean the P-trap and horizontal waste pipe to clear sludge.
• Regular maintenance: Run cold water for 20–30 seconds after each use to flush waste fully through the Rangemaster disposal and pipework.
