I recently bought an open-box Braun Oral B electric toothbrush on eBay, specifically for cleaning my handguns. Have had a chance to use it once so far, on one of my 22 lr revolvers, and it was very effective on areas where I would normally use a nylon brush. Knocked 15 minutes off my usual cleaning time! The brush head was shot after the one use, so I tossed that, but I ordered more (again, open box on eBay, so they're cheaper). Anyone else tried this?
