Method and Apparatus for a Ceramic Surface Mineral Deposit Scrapper

Abstract

A ceramic surface mineral deposit scrapper is used to remove mineral deposits from ceramic surfaces by scrapping the surface. The scrapper can be manufactured from plastic. A shaft of plastic is cut at an acute angle which provides a cutting edge that can extend over nearly a 108° arc. A handle is mounted to the other end of the shaft. The scrapper removes the mineral deposits without scratching the surface of the ceramic.

What is claimed is: 
     
         1 . A plastic scrapper apparatus comprising:
 a shaft with a first end, a second end and an outer surface;   an axis along the center of the shaft;   a handle coupled to the first end of the shaft;   a planar surface forming the second end of the shaft;   an acute angle greater than zero formed between the planar surface and the axis of the shaft; and   all acute angled edges formed between the outer surface of the shaft and the planar surface presents a cutting edge; wherein   the cutting edge can be used to remove a mineral deposit coating adhered to a surface of a ceramic object.   
     
     
         2 . The apparatus of  claim 1 , wherein
 the cutting edge is placed in contact with a interface between the ceramic object and the mineral deposit coating.   
     
     
         3 . The apparatus of  claim 2 , wherein
 a removal of the mineral deposit coating occurs when the shaft is forced to move along the surface of the ceramic object in any acute angled path with respect to a projection of the axis of the shaft onto the surface of the ceramic object.   
     
     
         4 . The apparatus of  claim 1 , wherein
 the shaft is cylindrical along its length.   
     
     
         5 . The apparatus of  claim 1 , wherein
 the shaft is oval along its length.   
     
     
         6 . The apparatus of  claim 1 , wherein
 the plastic scrapper apparatus removes all mineral deposits that formed on the surface of the ceramic object.   
     
     
         7 . The apparatus of  claim 1 , wherein
 the ceramic object is selected from the group consisting of a sink, a bathtub, and a toilet.   
     
     
         8 . A plastic scrapper apparatus comprising:
 a shaft having an outer surface surrounding an axis of the shaft;   a handle coupled to a first end of the shaft;   a second end of the shaft having a planar surface;   an acute angle greater than zero formed between the planar surface and the axis of the shaft; and   all acute edges formed between the outer surface of the shaft and the planar surface presents a cutting edge.   
     
     
         9 . The apparatus of  claim 8 , wherein
 the cutting, edge can be used to remove a mineral deposit coating adhered to a surface of a ceramic object.   
     
     
         10 . The apparatus of  claim 9 , wherein
 the ceramic object is selected from the group consisting of a sink, a bathtub, and a toilet.   
     
     
         11 . The apparatus of  claim 9 , wherein
 the cutting edge is placed in contact with an interface between the ceramic object and the mineral deposit coating.   
     
     
         12 . The apparatus of  claim 11 , wherein
 a removal of the mineral deposit coating occurs when the shaft is forced to move along the surface of the ceramic object in any acute angled path with respect to a projection of the axis of the shaft onto the surface of the ceramic object.   
     
     
         13 . The apparatus of  claim 8 , wherein
 the shaft is cylindrical along its length.   
     
     
         14 . The apparatus of  claim 8 , wherein
 the shaft is oval along its length.   
     
     
         15 . The apparatus of  claim 8 , wherein
 the plastic scrapper apparatus removes a mineral deposit that formed on the surface of a ceramic object.   
     
     
         16 . A plastic scrapper apparatus comprising:
 a shaft having an outer surface surrounding an axis of the shaft;   a handle coupled to a first end of the shaft;   a second end of the shaft having a planar surface;   an acute angle formed between the planar surface and the axis of the shaft; and   any acute angled edges formed between the outer surface of the shaft and the planar surface presents a cutting edge; wherein   a force can he applied to the cutting edge to remove a mineral deposit coating adhered to a surface of a ceramic object.   
     
     
         17 . The apparatus of  claim 16 , wherein
 the ceramic object is selected from the group consisting of a sink, a bathtub, and a toilet.   
     
     
         18 . The apparatus of  claim 16 , wherein
 the plastic scrapper apparatus removes the mineral deposit that formed on the surface o the ceramic object.   
     
     
         19 . The apparatus of  claim 16 , wherein
 the cutting edge is placed in contact with an interface between the ceramic object and the mineral deposit coating.   
     
     
         20 . The apparatus of  claim 19 , wherein
 a removal of the mineral deposit coating occurs when the shaft is forced to move along the surface of the ceramic object in any acute angled path with respect to a projection of the axis of the shaft onto the surface of the ceramic object.
