         9 . The composition of  claim 7  comprising greater than 0.0% and less than about 25.0% by weight cationic surfactant.  
     
     
         10 . The composition of  claim 1 , wherein the composition comprises a chelating agent.  
     
     
         11 . The composition of  claim 10 , wherein the chelating agent comprises at least one of a tripolyphosphate, a pyrophosphate salt, and a combination thereof.  
     
     
         12 . The composition of  claim 8  comprising greater than 0.0% and less than about 33.0% by weight chelating agent.  
     
     
         13 . The composition of  claim 3  comprising at least one of a nonionic surfactant, a cationic surfactant, and a chelating agent.  
     
     
         14 . A cleaning pre-mixture comprising: 
 premix A comprising a fatty acid methyl ester; and    premix B comprising a salt solution.    
     
     
         15 . The pre-mixture of  claim 14 , wherein premix A further comprises at least one of a nonionic surfactant, a cationic surfactant and a combination thereof.  
     
     
         16 . The pre-mixture of  claim 14 , wherein premix A further comprises a nonionic surfactant and a cationic surfactant.  
     
     
         17 . The pre-mixture of  claim 14 , wherein premix A further comprises at least one alkyl phenol having an alkyl group containing from about 8 to about 15 carbon.  
     
     
         18 . The pre-mixture of  claim 14 , wherein premix B comprises at least one of a metasilicate, a chelating agent and a combination thereof.  
     
     
         19 . The pre-mixture of  claim 14 , wherein premix B comprises a metasilicate and a chelating agent.  
     
     
         20 . The pre-mixture of  claim 14 , wherein premix B comprises at least one of a phosphate, a silicate, and combination thereof.  
     
     
         21 . A method of formulating a cleaning composition, the method comprising: 
 adding a fatty acid methyl ester to at least one of a nonionic surfactant, a cationic surfactant, a chelating agent, a silicate salt, a xylene sulfonate salt, a hydroxide base and a combination thereof to form the cleaning composition.    
     
     
         22 . The method of  claim 21 , further comprising adding a nonionic surfactant.
