Stopped tracking the Fusion ProShield I have at 128 shaves. That what late July and have switched back and forth with electric since that so do not know the real number.
I change Fusion Proglide cartridges after 30 two-pass (WTG+XTG) shaves. Mach3 Turbos after 20.
I rinse the cartridges in alcohol after every use and quickly strop them on a patch of denim.
What kind of alcohol do you use? Just everyday rubbing alcohol? What's the procedure, splash some on the cartridge or dip it in a bowl of the stuff? Tnx.
