Had previously had good experiences with an organic cleaners from another manufacturer. I can not say much about the cleaning action. My Braun Series 7 does not dry off. If I take the shaver out of the station the next day he is still wet. Thought the station had broken down and had Brown used a genuine cartridge. Now everything is back in order. Further remain blue residue on the shaving head. Unfortunately, I have bought in my euphoria and to save shipping costs 2 bottles. I will not vewenden. At least for the Series 7 I can not recommend this cleaner.
