There are some shiny flake like substances inside my carafe. What is it?

When the inner glass lining of the carafe contains hot water, the mineral content in the water attaches to the inner glass surface of the carafe and makes a thin film. This eventually breaks loose and floats in the water. These flakes are not harmful to the health and does not pose a health risk. If flaking occurs, the product can be cleaned with the steps below:

1. Dilute citric acid (10g) in lukewarm water and fill the carafe with water.
2. After a few hours, pour the solution out and wash the main body with a soft bristled brush.
3. Thoroughly rinse the main body and leave to dry completely.

Even when flaking does not occur, we recommend to clean the inner glass lining with this method periodically as a preventative measure. To purchase citric acid, please see our support section to visit our online spare parts store and select your model.
