A method, system and cleaning solutions for the ultrasonic cleaning of drill cuttings and the resulting cleaned drill solids is described. The drill cuttings are characterized by their liquid/solid composition, texture of solids and size of particulates. A cleaning solution formula having surfactant(s) and viscosity agent(s) is selected based on the characterization of drill cuttings. Drill cuttings are contacted with the selected cleaning solution and subjected to ultrasonic vibrations simultaneously for a period of treatment and vibration time. Contaminants from drill cuttings are removed to beneficial use standards and the resulting cleaned drill solids may be reused at the well site. The cleaning may occur at a well site in conjunction with drilling activity and the cleaning solution may be changed to adapt to changes in the drill mud and/or cuttings characteristics.
