The present invention relates to a composition and a method of cleaning 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, an extreme pressure lubricant and surfactants. The method for cleaning mill gears 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, an extreme pressure lubricant and thickeners to the area to be cleaned, continuously applying the solution to contact the surface and penetrate and dissolve the surface grease, and thereafter rinsing the surface to remove the dissolved surface greases and the cleaning composition. The initial spraying is carried out during use of the mill gear whereas the rinsing is carried out as the mill gear is inched. The present invention provides a composition which dissolves gear lube accumulations effectively and in an environmentally acceptable manner as well as a method of cleaning mill gears resulting in significant savings in terms of labor and downtime of the equipment. The solution is safe to use on painted surfaces and emulsifies quickly when sprayed with water-soap solutions.

A process for producing a solid foaming agent, and a process for using the foaming agent for the removal of water from flooded gas wells is provided. The foaming agent is formed by first combining a water soluable, nonionic polyethoxylated surfactant with urea to form a solid urea adduct, and compressing the urea adduct under high pressures into a shape of size and density to enable it to drop to the bottom of a column of water existing in the well. The urea adduct is dropped into the flooded well bore and gas produced through the water generates foam which is expelled from the well with the gas flow.
