Welcome to the Tool of the Week crust removal Independence Day edition. The battery post and terminal cleaner brush is really two tools in one. The lower part of gizmo is full of stiff wires that clean up battery posts in short order with a few twists of the handle. An opposite twist of the handle reveals that inside the housing is a bristling porcupine of added utility! Cleaning corrosion from the inside contact surfaces of the terminals is the second use of this multiple purpose tool. The 2-in-1 reversible nature and long years of utility provided by this simple brush make it a required addition for anybody that owns a machine with one or more lead-acid batteries in the mix.
I stuck my finger into one of those as a little kid.
It did not go well.
@Mad_Science – hahaha. I’ll admit I was tempted too 🙂
