I observed that limescale in the Xiaomi Smart Kettle is possible to easily remove just by scrapping. So I designed tool to quickly remove most of it from the kettle.
This will not completle clean the Kettle, however it removes most of the limescale from the Kettle, so you will need then significantly less acid/vinegar and time to clean the kettle.
