Need to clean battery, lens, flash, or other metal contacts that have surface oxidation degrading contact? Forget about pencil erasers and their messy rubbings, or lemon juice that can drip into inconvenient places. Instead, use a suede brush from your local shoe store. The soft brass bristles, designed to gently raise suede nap, will delicately abrade the surface of any contacts-without overdoing it. Plus, they're small enough to carry easily in your bag or vest.
