DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a liquid detergent composition for hard surfaces for cleaning surfaces made of hard materials, such as car bodies, and a method for cleaning hard surfaces. More specifically, the present invention relates to a liquid detergent composition with which one can wash a hard surface having a particulate solid dirt thereon, without causing marring of the surface by the particulate solid dirt, and make the surface clean and can wash it, without pre-washing by water and the like, directly in a small amount of a liquid, and relates to a method for cleaning the hard surfaces.
PRIOR ART
In washing a hard surface, for example car body, having thereon particulate solid dirt resulting from house dust, soil, earth sand and the like according to the prior art, it was necessary in order to protect the surface from being marred by the dirt that while the dirt is removed from the surface with an excess of water or a detergent solution or after it had preliminarily been removed therefrom, the other stains were removed. Further, there occurred a problem that the hard surface was marred also by the material used in wiping the surface, e.g., cloth, paper, non-woven fabric, sponge or the like. However, there are lots of cases that the places where a hard surface to be generally an object of washing is present does not permit the use of a large amount of water, or the use of a large amount of water remarkably lowers the workability, even if it was possible. This is true of all of the commercially available current detergents for the purpose of use to the hard surface.
It is generally known that lubricants are used for preventing marring to the hard surface due to friction between solid particles and the hard surfaces, in which, in general, the surfaces of solid particles and the hard surface are adsorbed by the lubricants to form local pressure lubricant membrane, thus marring is prevented. Therefore, such a lubricants that have high adsorptive activity to both solid particles and hard surfaces and are not destroyed in the resulting adsorbing membrane thereof under local pressures are required. To the lubricants mentioned above it is essential matters that molecular structures of the lubricants are never deformed under local pressures and friction among moleculars is small.
However, when such a lubricant, having higher adsorptive activity and higher preventing ability for marring, is applied to a surface to be washed, the lubricant as such would remain thereon as soil. For example, grease which is believed to be advantageous in anti-marring properties has problems that the anti-marring properties are poor when the grease is wiped off the surface by a hand method and that the grease per se remains as a stain, therefore, eliminating the dirt can not be achieved. Moreover, the higher the anti-marring property of the lubricant is by making the lubricant membrane hard to be destroyed under a localized pressure, the bigger the shearing resistance of the lubricant becomes during wiping process with cloth, so that the workability is reduced as much as the level that it is actually impossible to working, even wiping off such an area of as small as 0.1 m.sup.2.

Those technologies are a lusturing composition mainly of wax, but are not intended to deterge the surface soiled with solid particles.
SUMMARY OF THE INVENTION
Under these circumstances, the object of the present invention is to provide a detergent composition for hard surfaces which can deterge a hard surface having a particulate solid dirt thereon without marring the surface even when no pre-washing is conducted and a large a
