I have notice that everybody wants a recurring income on products they
make like the braun razor CCR2, $13 to $17 for cleaning refills. Can I
refill myself and what exactly
should be used  and how often with the same cartridge before replacing ?  

Thanks Chris

Fill the dry cleaning cartridge with Isopropyl alcohol between ¨ø
and ¨ú up to the top. If you wish you can add a few drops of real
lemon juice to cover the smell of the alcohol and possible aid in the
dissolving of facial grease
