Do keep your garbage disposal clean. Pour a little dish soap inside and let the garbage disposal run for a minute or so with some cold water after washing dishes.
Do run your garbage disposal regularly. Frequent use prevents rust and corrosion, assures that all parts stay moving and prevents obstructions from accumulating.
Do grind food waste with a strong flow of cold water. Why cold water? It will cause any grease or oils that may get into the unit to solidify so that they can be chopped up before reaching the trap.
Do grind certain hard materials such as small chicken and fish bones, egg shells, small fruit pits, etc. A scouring action is created by these particles inside the grind chamber that cleans the garbage disposal’s walls.
Do cut large items into smaller pieces. Put them into the garbage disposal one at a time instead of trying to shove a large amount in at once.
