Cups in the dishwasher do not get clean

Why the cups don't get clean

Many initially think that the leftovers in the cups must have dried up. That can be a cause of the problem. If you have the dishwasher rarely in operation, that could be because of that.

• The more common problem is that the tea residues (especially black tea) are stubborn and won't get clean through the rinsing process. The tea sets strongly as it bonds with the water minerals and then does not dissolve.
• Another reason could be that the machine is dirty. A greasy dishwasher or clogged spray nozzles cannot guarantee full performance and stubborn dirt remains. In the worst case, a greasy layer will form on the dishes.
• Toppings made of salt or lime can ensure that the dishes come out of the machine "milky" and "matt".

Clean the dishwasher

• To make sure it's not the fault of the machine, you should clean it regularly. Check the spray glands every few months and do a thorough cleaning once or twice a year. There are special cleaners for this, with which an empty rinsing process is carried out. If that is the case, the cups will be clean again afterwards, because the greasy deposits are avoided.


Dishwasher cleans poorly - what to do?

Nowadays the dishwasher replaces hard manual labor. That’s why it’s all the more ...

• If the dishwasher is older and generally no longer cleans as well, you can put half a lemon in the cutlery tray. The citric acid makes the dishes clean, shiny and smelling pleasantly fresh and bacteria in the machine are also killed.
• If deposits occur due to salt or limescale, you should check whether the flap for the dishwasher salt is properly closed. Limescale deposits occur when the water is too hard and the water softener does not work properly. Check the setting and clean it with citric acid.
• Sometimes it helps to change the dishwasher tabs. Some are dosed more heavily than others and manage the problem with ease. An austerity program should be avoided, as this is usually not intensive enough.

Soak the cup or rinse by hand

If none of this works, you can be sure that it is not the machine. Further steps are necessary.

• So that the residue does not settle heavily on the cup, it is advisable to turn the machine on quickly after loading or to let the cups soak beforehand.
• Sometimes the deposits are too tight. The easiest thing to do with this problem is then to clean the cups by hand. The dirt will disappear by itself if you mix water and oxygen bleach (also works with baking soda and baking soda) in the cup and let it work for a few minutes. Then rinse the cup with a cloth and / or a brush and your problem is eliminated. Another method is scouring milk. She "peels" the dirt out of the cup with a sponge. This eliminates tea and coffee residues.

Regardless of which method you choose, with the tips listed above you will soon be able to look forward to clean cups again.
