Pallo Grinder Minder Brush
The Pallo Grindminder is a double-ended brush. On one side is a grinder brush. On the other side is a countertop brush. The countertop brush has a low profile so that it's easy to sweep under countertop equipment - like the espresso machine, which should have a 4-inch clearance.
It features an ergonomic handle to keep your hand in a comfortable, natural position. And it has natural, food-grade birstles, which excel at collecting both large and small grinds. The brush has three rows of stiff nylon bristles to provide plenty of sweep for your counters.
Note the hanger hole in the upper corner, which makes it easy to hand from a peg. You can attach it to a cord as well.
