Use this Craftsman battery brush to remove corrosion and dirt from battery terminals and cable clamps. The external brush clean cable clamps well while the internal one does a great job in cleaning terminal posts. The high-impact, plastic case will not corrode, and brush will not soften in cleaning solutions.
I bought this tool to keep my battery cables cleaned so that I don't have a problem with the car starting due to corrosion this winter. This tool works great and will be used often for preventive maintenance.
