The Braun 3-in-1 Shavercare cleaning liquid hygienically cleans your shaver by removing hair residues and skin particles. It is the world's first alcohol-based cleaning system for shavers that hygienically cleans your electric shaver, 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 shaver feels like new every day, you should replace the cleaning cartridge every two months, based on an average of 5 shaves per week, designed for 20 cleaning cycles.
