Abstract
In a method of cleaning a rotary mixing device having a mixer portion and a driving shaft, a shield is located over at least the mixer portion. The mixing device is rotated, expelling material clinging to or trapped by the mixing portion, such as paint, from the mixer portion of the mixing device. This material is blocked or caught by the shield. In one embodiment, the shield is cylindrical in shape and has a base with an opening through which the shaft of the mixing device may extend, and an open second end leading to an interior area for containing the mixer portion of the mixing device.
