Advanced rust remover
SUMMARY OF THE INVENTION 
     The combination of a pulley, an engine and a cleaning strip. The engine includes a belt with the pulley having a circumferential groove and formed of a material that rusts or gets dirty. The system disclosed herein is particularly suited to cleaning the pulley&#39;s of a marine engine. The cleaning strip is rectangular in configuration, is adapted to be bent longitudinally and has an abrasive side and a non abrasive side, which may have an adhesive associated therewith. The belt is positioned on the external circumference of the pulley with the abrasive side, sand paper, for example of the cleaning strip abutting the pulley and the non abrasive and adhesive side abutting the belt. The cleaning strip is movably positioned between the external circumference of the pulley and the belt. As the engine operates, the belt and the pulley move causing the abrasive side of the cleaning strip to pass through and around the circumferential groove. Since the abrasive side of the cleaning strip is moving at high speed, it abrades away any dirt, rust or contaminant which may have adhered to the circumferential groove. If the dirt, rust or contaminant are not removed, the engine may break down with the resultant cost to repair the engine and loss of productive time.

     DESCRIPTION OF THE PREFERRED EMBODIMENT(S) 
     There is shown in the drawings an engine 10, which includes pulleys 12 and belts 14. The pulleys 12 each includes a circumferential groove 16 within which one of the belts 14 is positioned and the pulleys 12 may also be formed of a material that rusts, a metallic substance, for example. Buildup of dirt, rust and other contaminants occurs on the pulleys 12 reducing their efficiency in moving the belts 12 and may cause failure of the engine. In the past, it was necessary to use a flat head screwdriver or some similar instrument to manually clean the pulleys 12 of such a contaminated engine. This work was extremely difficult and dangerous. The pulleys 12 may also be formed of plastic. 
     The applicant&#39;s advanced rust remover comprises a cleaning strip 18 having an abrasive side 20 and a adhesive sides 22. The cleaning strip 18 includes some type of adhesive which will allow removable adherance of the cleaning strip 18 to the belt 14. 
     To clean a metallic or plastic pulley 12 of an engine 10 with the belt 14 partially positioned in the circumferential groove 16 of the pulley 12 and with the pulley 12 and the belt 14 adapted to move. The cleaning strip 18 is removably positioned on the lower surface of the belt 14 utilizing its side 22 and leaving its abrasive side 20,, for example, facing away from the belt 14. The abrasive side 20 of the cleaning strip 18 will at some stage of the movement of the belt 14 pass over the circumferential groove 16 of the pulley 12 cleaning any dirt, rust and other contaminants at a fraction of the time it would take to clean the pulley 14 manually without the attendant dangers of a manual cleaning. When the cleaning is completed the cleaning strip 18 is stripped from its engagement to the belt 14.
