Surface cleaner is a cleaner, which is used to clean the surface. It cleans the hard and dirty surfaces. It has a clean, citrus scent with professional strength cleaning. It removes surface stains resulting from spilled petroleum products on concrete, asphalt, rock, and soil.

Surface coating is a mixture of film-forming materials plus pigments, solvents, and other additives. It forms a thin film, when it is applied on any object. Surface coating includes, paints, drying oils and varnishes, synthetic clear coatings, and other products whose primary function is to protect the surface of an object from the environment.

The surface engineering process modifies the surfaces of engineering components to improve their in-service performance, useful working lifetimes, aesthetic appearance or economics of production. It means modifying the surface of a material or component to confer surface properties, which are different from the bulk properties. The purpose of this process is to minimize corrosion, reduce frictional energy losses, reduce wear, act as a diffusion barrier, provide thermal insulation, exclude certain wavelengths of radiation, promote radiation electronic interactions, electrically insulate or simply improve the aesthetic appearance for the surface.
