Rub the bristles of shoe brushes together in a warm soapy solution to which a little turpentine has been added. Care should be taken to hold the brushed under the surface of the solution, otherwise the bristles will cause the solution to spray in tiny drops over the face and arms.
Rinse in a fresh soapy solution, shake thoroughly and place in open air to dry.
