Final answer:
To use a dishwashing machine correctly, one must select the appropriate dishwasher detergent, remove leftover food from dishes, load the dishwasher to allow water to reach all surfaces, and avoid washing incompatible materials such as silver and brass in the machine.
Step-by-step explanation:
The proper guidelines for using a dishwashing machine include several steps to ensure both cleanliness and the longevity of your dishes and the dishwasher itself. First, it is crucial to select a special detergent made specifically for dishwashers, which differs from hand dishwashing liquid. Pre-rinsing or scraping leftover food from dishes is a preliminary step before placing them in the machine.When loading the dishwasher, make sure that the surface of all dishes is open to the flow of water, avoiding overcrowding to enable thorough cleaning. Most dishwasher detergents are incompatible with materials such as silver, brass, cast iron, and others, so these items should be washed by hand. Additionally, modern dishwasher detergents may contain ingredients such as bleach, enzymes, and rinsing aids, and come in various forms including gels, liquids, powders, and tablets.It is also important to remember that dishwashing detergents can be formulated to work under different conditions such as cold or sea water, though hot water typically yields the best results. There are environmentally friendly detergents available, known as biodegradable detergents, which may be better for the environment than conventional ones.
