Abstract
Abstract A method of cleaning and polishing a variety of porous and non-porous materials including porcelains, plastics, marble, glass, and finished wood. The polishing compound is comprised of an abrasive powder, an hydroflouric acid, and an organic solvent. The polishing compound is applied with a cloth and scouring of the surface to be cleaned and polished is accomplished with a soft cloth or with a polishing machine. The invention effectively removes scratches, stains, and blemishes from the surface to be polished and after scouring the result is a blemish free and polished surface.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
A method of cleaning and polishing dull or blemished porous and non-porous surfaces comprising: (a) applying to the surface to be cleaned and polished a polishing compound prepared by a method comprising: providing a container not labile to the acid used; adding an abrasive powder to the container; adding an organic solvent to the container; adding hydrofluoric acid to the container to produce a reaction which forms a gas and a damp powder residue which can be used as a polishing compound without any further processing; (b) application of a scouring action to the surface using the polishing compound; and (c) removal of the polishing compound from the cleaned and polished material.
Claim 2
Independent Claim
112 words
A method of cleaning and polishing dull or blemished porous and non-porous surfaces comprising: (a) applying to the surface to be cleaned and polished a polishing compound prepared by a method comprising: providing a container not labile to the acid used; adding an abrasive powder to the container; adding an organic solvent to the container; adding hydrofluoric acid to the container to produce a reaction which forms a gas and a damp powder residue which can be used as a polishing compound without any further processing; (b) application of a scouring action to the surface using the polishing compound; and (c) removal of the polishing compound from the cleaned and polished material.
Claim 3
Dependent Claim
15 words
The method of claim 1 where the abrasive powder used is a silica based powder.
Claim 4
Dependent Claim
32 words
The method of claim 1 where the surface is comprised of a material selected from the group of porous substances consisting of: porcelain, fiberglass, acrylics, granite, marble, synthetic marble, and finished wood.
Claim 5
Independent Claim
68 words
A method of preparing a polishing compound comprising: (a) providing a container not labile to the acid used; (b) adding an abrasive powder to the container; (c) adding an or solvent to the container; and (d) adding a hydroflouric acid to the container to produce a reaction which forms a gas and a damp powder residue which can be used as a polishing compound without any further processing.
Claim 6
Independent Claim
68 words
A method of preparing a polishing compound comprising: (a) providing a container not labile to the acid used; (b) adding an abrasive powder to the container; (c) adding an or solvent to the container; and (d) adding a hydroflouric acid to the container to produce a reaction which forms a gas and a damp powder residue which can be used as a polishing compound without any further processing.
Claim 7
Dependent Claim
15 words
