If tea, coffee, or lipstick stains persist on dishes after washing in your Grundig Dishwasher: * Select a program with a higher temperature and cycle time. * Surfaces of deteriorated kitchen utensils may not be suitable for dishwashers. * If using powder detergent, ensure it is stored in a closed container in a non-humid environment, or switch to tablet detergents.
