The Braun 3-in-1 Shavercare Cleaning Liquid hygienically cleans your razor by removing hair residues and skin particles. It is the world's first alcohol-based cleaning system for razors that hygienically cleans your electric razor, enhances performance, and protects the blade. This is an original product from Braun, developed in Germany. It is 100% compatible with any Braun Smartcare Center as well as any other Braun cleaning station. To ensure your razor feels fresh every day, you should replace the cleaning cartridge every two months (after every second shave, based on an average of 5 shaves per week, designed for 20 cleaning cycles).
