Abstract
A method for cleaning uncured oil-based paint and varnish from paintbrushes and other painting tools utilizes a cleaning composition produced by blending vegetable or mineral oil with emulsifying surfactants in the preferred ratio of from 85% -50% oil to 50% -15% surfactants, the composition is preferably water free. The cleaning composition is applied to the brush or tool and worked in for about 30 seconds. The brush or tool is then rinsed with water for about 1 minute. The procedure is repeated until the brush or tool is substantially free of paint.
