Unfortunately, I can't provide any information on this. I have always used the original until now. The shaver comes with a portion, I would compare this with the Biochem shaving head cleaner, consistency etc. I think it is important that it does not start foaming and is mixed with water like the original, then I see no problem. With something alcohol-based I would be careful, it could attack the seals.

How long does a bag of cleaning fluid last? If I now shave every 1 - 2 days and then start the cleaning process.
