The present invention relates to a cleaning composition for cleaning of lubricated surfaces subject to residual buildup such as large mill gears, shovels and draglines. The composition comprises at least one terpene being capable of dissolving or softening hardened lubricants and residuals, hydrocarbon solvent, and surfactants. The composition is preferably compounded to be of sufficient viscosity to remain in contact with generally vertical surfaces for sufficient time to result in the loosening of lubricants and residuals attached thereto. In an aspect of the invention, a method for cleaning of such equipment and in particular a method of cleaning mill gears is provided. The method comprises applying a solution comprising at least one terpene being capable of dissolving or softening soils containing grease or oil, aliphatic hydrocarbon solvent, biodegradable surfactants and thickeners to the area to be cleaned, allowing the solution to remain in contact with the surface for sufficient time for the solution to penetrate and dissolve the surface grease and thereafter rinsing the surface to remove the dissolved surface greases. The present invention provides for a method and a composition which dissolves gear lubes and greases consequently resulting in significant savings in terms of labour and downtime of the equipment. The solution is safe to use on painted surfaces and emulsifies quickly when sprayed with water-soap solutions.
