THE CLAIMS
What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows :
1. A method of removing contaminants from the exterior surfaces of an automotive vehicle, which comprises :
(a) forming a wad of a rubbing composition that can be held conveniently m the palm of the user's hand and has external surfaces shaped to contact the surface to be cleaned, said rubbing composition having a putty- like consistency, being substantially free of water, and consisting essentially of the following ingredients in the indicated amounts:
(l) about 1% to about 8% by weight of a material selected from the group consisting of fatty acids containing 16 to 20 carbon atoms and fatty esters containing 12 to 18 carbon atoms;
(ii) about 20% to about 60% by weight of a fine abrasive;
(in) about 15% to about 50% by weight of a polybutylene; and
(IV) about 15% to about 50% by weight of an oil absorbent filler;
(b) applying a water solution of a detergent to a given area of the surface that is to be cleaned;
(c) then rubbing said given area with said wad of rubbing composition;

(d) continuing said rubbing until the contaminants are loosened from the surface being cleaned, are caused to adhere to the wad of rubbing composition, and are thereby removed from the surface; and
(e) thereafter removing any residue of the rubbing composition that may remain on said given area of the surface being cleaned.
2. The method of claim 1 in which the user of the rubbing composition removes any residue of the rubbing composition that may remain on said given area of the surface being cleaned by wiping said area with a soft piece of water absorbent material .
3. The method of claim 1 in which the user of the rubbing composition reworks the wad from time to time by manually squeezing and folding the wad of material to expose new portions of the wad to be rubbed across the surface being cleaned.
4. The method of claim 1 in which the fatty acid in the rubbing composition is selected from the group consisting of oleic acid and linoleic acid.
5. The method of claim 4 in which the fatty acid in the rubbing composition is oleic acid.
6. The method of claim 1 in which the fatty ester in the rubbing composition is a methyl ester derived from a material selected from the group consisting of vegetable and animal fatty acids.
7. The method of claim 1 in which the fine abrasive is finely divided calcium carbonate.

polybutylene is an oil.
9. The method of claim 1 m which the oil absorbent filler is magnesium silicate.
10. The method of claim 1 in which the rubbing composition consists essentially of the following ingredients in the indicated amounts :
(a) about 1% to about 5% by weight of a material selected from the group consisting of fatty acids containing 16 to 20 carbon atoms and fatty esters containing 12 to 18 carbon atoms;
(b) about 20% to about 60% by weight of a fine abrasive ;
(c) about 20% to about 40% of a polybutylene; and
about 20% to about 40% of an oil absorbent filler.
11. The method of claim 10 in which:
(a) the fatty acid is oleic acid;
(b) the fine abrasive is finely divided calcium carbonate;
(c) the polybutylene is an oil polymerized at about 32°F. (0°C.) to about 77°F. (25°C), and
(d) the absorbent filler is magnesium silicate.
12. The method of claim 11 m which the rubbing composition contains up to about 1.0% by weight of titanium dioxide .
13. The method of claim 11 in which the rubbing composition consists essentially of the following ingredients in the indicated amounts:
(a) about 5% by weight of oleic acid;
(b) about 40% by weight of finely divided calcium carbonate;
(c) about 30% by weight of a polybutylene oil polymerized at about 32°F. (0°C) to about 77°F. (25°C) ; and
(d) about 25% by weight of magnesium silicate.
