I just checked a cleaning kit on amazon and it's literally just a blank cartridge with included contact cleaner for $30, it's literally the same thing as using a free sports game plus contact cleaner from the hardware store.
It will also work on any cartridge system, if a game is bad you can just use some qtips and contact cleaner or use a dead console as the friction cleaner.
I guess those cartridge cleaner things are bogus?
