Abstract
Methods of cleaning equipment such as hand tools dirtied by bituminous mixture. A biodiesel emulsion comprising biodiesel, water and emulsifier(s), is applied to the surface of the equipment for a period of time (e.g., at least about 15 minutes) and optionally agitated. The biodiesel emulsion produces cleaning properties comparable to straight biodiesel, at a cost reduction, due to the replacement of biodiesel with water.
