Method for cleaning floor drains

Abstract

A method for controlling Listeria in floor drains wherein an aqueous solution composed of a chlorinated caustic material which is soft metal compatible is introduced into a drain where Listeria is present. In a preferred manner, the aqueous solution is introduced into the drain employing a hose end dispensing device having a foam producing nozzle. The resulting aqueous solution has a sufficient viscosity to remain in the drain for about 30 seconds to 10 minutes.

1 . A dispenser containing a dilute foamable composition for controlling Listeria in drains comprising: 
 a container containing a cleaning agent comprising: 
 a. a caustic cleaner  
 b. a blend of surfactants  
 c. a hypochlorite  
 d. water; and  
   dispensing means operatively associated with the container to dispense the cleaning agent from the container when connected to a hose for delivering water to the dispensing means.    
   
   
       2 . The dispenser of  claim 1  wherein the dispensing means includes an eductor.  
   
   
       3 . The dispenser of  claim 1  wherein the dispensing means is vented.  
   
   
       4 . The dispenser of  claim 1  wherein the dispensing means includes a foam producing nozzle.  
   
   
       5 . The dispenser of  claim 1  wherein the cleaning agent includes silicates.  
   
   
       6 . A dispenser for controlling Listeria in drains comprising: 
 a container containing a dilute foamable cleaning agent capable of controlling Listeria; and    dispensing means operatively associated with the container to dispense the cleaning agent from the container when connected to a hose for delivering water to the dispensing means.    
   
   
       7 . The dispenser of  claim 6  wherein the dispensing means includes an eductor.  
   
   
       8 . The dispenser of  claim 6  wherein the dispensing means is vented.  
   
   
       9 . The dispenser of  claim 6  wherein the dispensing means includes a foam producing nozzle.  
   
   
       10 . The dispenser of  claim 6  wherein the cleaning agent includes silicates.  
   
   
       11 . A dispenser for cleaning drains comprising: 
 a container containing a drain cleaning agent; and    dispensing means including a hose end sprayer operatively associated with the container to dispense the cleaning agent from the container.    
   
   
       12 . The dispenser of  claim 11  wherein the cleaning agent is a liquid.  
   
   
       13 . The dispenser of  claim 12  wherein the dispensing means includes a nozzle.  
   
   
       14 . A method of controlling Listeria in drains employing the dispenser of  claim 1 .  
   
   
       15 . A method of controlling Listeria in drains employing the dispenser of  claim 6 .  
   
   
       16 . A method of cleaning drains employing the dispenser of  claim 11.
