How to clean my Mayu Swirl?

The carafe is waterproof and dishwasher safe. If you see remnants of scale after regular hand/dishwasher use, don't fret! Add one teaspoon of Citric Acid to the carafe and fill with warm water. Place on Mayu swirl base and let it spin until you see no trace of scale on the carafe walls. Empty the carafe and wash.
To clean the impeller from stains, add one cup of water and one spoon of bleach. Let it rest during the night, then flush away the bleach and wash well with water and soap.
