Whirlpool garbage disposal emits persistent foul odors even after use.

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

• Clean splash guard: Remove the Whirlpool splash guard (if removable) and scrub both sides with hot soapy water and a brush.
• Clean chamber: Pour a mixture of baking soda and vinegar into the disposal, let it foam for several minutes, then flush with hot water.
• Grind ice and citrus: Run a tray of ice cubes and small citrus peels through the disposal with cold water to help scour the shredder ring.
• Flush drain: Run hot water for several minutes to flush the discharge line and P-trap.
• Repeat regularly: Perform this cleaning routine periodically to prevent odor buildup.
