The Cuisipro Magnetic Spot Scrubber is an ingenious invention that helps you clean dried spots on glass in hard to reach places. Have you ever tried cleaning every last spot inside a glass bottle with a narrow neck? You can’t reach in with your fingers or shove in a brush, and it drives you nuts when all the soap and water in the world doesn’t budge that obstinate spot at the bottom of the bottle. The solution can be found in the laws of physics, by making use of two magnets that are attracted to each other. Both the scrubber and the handle have nubbed rubber scrubbers. You drop the scrubber into the glass container, and guide it to the spot using the handle from the outside. Move it around on the spot, and it’s gone.
