Refills cartridges with an alcohol based cleaning solution and fresh lemon scent.
Braun is the only brand using alcohol cleaning fluid which eliminates 99.999% of all germs and bacteria in every cleaning process. Tests have shown that using the cleaning center is 10 times more hygienic than simply rinsing it under tap water.
A Clean & Renew refill cartridge should be replaced around 4 times a year and makes your shaver feel like new every day.
