Gabe's Pride Shower Track / Grout Brush is a super-handy tool for getting those hard to reach spots like around your faucets, knobs, and shower door tracks. It makes cleaning shower door tracks and working around sink faucets and knobs effortless. Whether scrubbing shower corners or around soap dishes and brackets, the bristles help scrub those really hard to reach areas.

I would not recommend this for your teeth but it sure will save your fingers and knuckles in tight spaces!
