It is important to use dishwasher detergent specifically designed for use in dishwashers, rather than regular dish soap or liquid soap. Dishwasher detergent is formulated to produce fewer suds and is more effective at removing food particles, grease, and stains from your dishes. It also contains enzymes and other additives that help to break down and remove food residues, whereas regular dish soap may create excessive suds that can overflow from the dishwasher and potentially damage the appliance. Additionally, dish soap may not provide the same level of cleanliness and shine that dishwasher detergent offers. Therefore, it is better to use dishwasher detergent for optimal results when using a dishwasher.
