Over time, your basket strainer will collect some dirt and grime, so you will need to clean it periodically. HERE'S OUR TRICK: Put a level teaspoon of powdered dishwasher detergent onto the closed basket strainer Pour approx. 250 ml of boiling water over the strainer and let it soak for a few minutes Scrub it with a dish washing brush until the basket strainer and drain cup are shiny Open up the basket strainer and take out the basket insert Scrub the opening of the drain cup Rinse it with clean warm water
