Article in English: The number one rule when it comes to garbage disposals is to avoid putting anything down there which is not biodegradable. The garbage disposal is not a trash can, and using to get rid of unsuitable items is a recipe for disaster. You can minimize damage and cut down on cleaning time by only using the garbage disposal for biodegradable food items. Things you should avoid putting down there include:  Fibrous materials such as onion skins, corn husks, artichokes and celery stalks. These can get tangled in the motor, so compost them instead. Starchy materials like potato peels. The starch may form a thick paste, causing the blades of the garbage disposal to stick. Expandable food such as rice or pasta. These may expand from the water and clog the drains. Coffee grinds can also clog the drains. You can, however, grind up items such as egg shells, small fish or chicken bones, and small fruit pits, as these will actually help in cleaning the garbage disposal. A mistake many people make is turning off their garbage disposal as soon as the grinding noises stop. It is better to leave the garbage disposal on (with the water running) for several seconds after the grinding noises subside, as there may still be small particles in the disposal unit which have not yet been cleared away. It is not a good idea to pour any kind of oil, grease or fat into your garbage disposal. The grease can accumulate in the disposal unit, slowing down the motor and lining the pipes, causing the drain to clog. Try to wipe off as much grease as possible from pans and roasting tins using paper towel, before rinsing. You can prevent large pieces of food from becoming stuck in your garbage disposal by cutting them into smaller pieces first. This is true for pieces of fruit and veg, or anything else you think your garbage disposal might have a hard time processing.
