Abstract: Cleaning compositions and methods of use thereof are described. A representative method includes treating equipment, particularly equipment used in the asphalt industry and other industries, such as bituminous, rubber, plastics, polymer, tar, concrete, and cement industries. The methods employ a cleaning composition that includes at least one or more of the following: surfactants, builders, hydrotropes, alkali compounds, processing aids, organic acids, and water conditioners, in any combination.

Abstract: Systems and methods for cleaning asphalt contact surfaces are provided. One such system includes a means for determining a dilution ratio appropriate to a particular asphalt contact surface, a nozzle proximate to the asphalt contact surface, and a pump in fluid communication with the nozzle. The pump is configured to deliver to the nozzle a mixture of water and said cleaning compound with the appropriate dilution ratio. One such method includes the steps of: pumping a cleaning mixture with a dilution ratio appropriate to a particular asphalt contact surface; supplying said pumped cleaning mixture to at least one nozzle proximate to the asphalt contact surface; and spraying the asphalt contact surface through the nozzle with the pumped mixture.

Abstract: Cleaning compositions and methods of use thereof are described. A representative cleaning composition includes about 0.2% to about 25% of a surfactant and one or more of the following components: about 5% to about 99% of a builder, bout 5% to about 95% of a hydrotrope, about 2% to about 60% of a water conditioner, about 0.1% to about 35% of an alkali, and about 2% to about 85% of a processing aid.
