Review on Z Red S504 Battery Cleaner by Nick Moo

Dropped my old cleaner in the engine bay and had this bought as a replacement. Typically, post-cleaners have a limited lifespan due to their construction. I like plastic pole cleaners much more than metal ones because of the corrosion issues. This post cleaner has an aggressive cutter instead of wire bristles, I actually like the all bristle version more than the cutter version because the bristles in the battery pin connector are less aggressive. Generally does what is expected with no real problems.
