When choosing a commercial dishwasher, one of the most important features is its cleaning efficiency. The dishwasher should thoroughly clean dishes, utensils, and glasses, removing stubborn stains, food residues, and bacteria. Check if the dishwasher offers various cleaning programs and cycles, and if it has built-in special features such as soaking, pre-washing, or adjustable detergent dosing. It is also important to verify if the machine uses appropriate water temperatures and pressure to achieve high hygiene standards.
