A grease trap requires regular cleaning and maintenance, and the most common way to do this is to use an enzyme-based cleaner. Enzyme-based cleaners contain bacteria and enzymes that break down the grease, fats, and oils that accumulate in the trap, allowing them to be washed away in the wastewater. Plus, a small amount of dish soap can be added to the trap, as it helps to break up the grease and make it easier to remove.
