A pivot portion is between a handle portion proximally and a brush portion distally. The brush portion has first and second twisted wires. Each twisted wire has a loop distally and linear ends proximally. The linear ends are coupled to the handle portion. Each loop is arcuate for between 270 and 360 degrees with a common side axis when viewed from the side. Each loop is arcuate for between 90 and 180 degrees with a front axis between the twisted wires when viewed from the front. Each loop is arcuate for between 90 and 180 degrees with parallel top axes spaced laterally from the twisted wires when viewed from above. Each loop has bristles extending radially for 360 degrees from the loop.
