Remove tar rims from the cup with salt
- The more calcareous the water, the faster the tar rims form in the cup. The dishwasher often fails to remove the edges. The reason is the lack of friction.
- Fill the cup with warm water and put some salt on a cloth. Gently rub the salt into the edge of the tea.
- Depending on how persistent the stain is, you may need to rub the salt in for a shorter or longer time. You can then rinse the clean cup again with water.

- Put one of the substances in the cup with warm water and let the mixture work overnight. You can then loosen the edges of the tar with a cloth or your finger.
