Run cold water while operating the garbage disposal. The cold water will help solidify greasy food waste so that the garbage disposal can chop up this waste.
Allow a strong flow of cold water to continue running for 30 seconds after turning off the garbage disposal. This will effectively flush out any remaining food particles in the drain.
Remove small items that could fall into the garbage disposal, such as silverware, from the sink before turning on the garbage disposal.
Run the garbage disposal shortly after you put food in it. Do not allow food waste to build up in the garbage disposal.
