HOW TO CLEAN A GARBAGE DISPOSAL

To get rid of bad odor from a garbage disposal grind 1-2 gallons of ice while running hot water. If odor persists, add 1 level cap or 1 envelope of Smelly Dishwasher & Disposal Cleaner to a pail of hot water and pour the mixture down the drain before retiring for the night. In the morning grind another gallon of ice while running hot water.

Another cause of odor can be an improperly installed P or S trap under the sink
