Method for cleaning floor drains
View Patent ↗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 method of controlling Listeria in drains comprising:
introducing into a drain wherein Listeria is present, a dilute foamable composition containing a cleaning agent comprising:
a. a caustic cleaner
b. a blend of surfactants
c. a hypochlorite; and
d. water
the introduction of the composition in the drain being effected by a hose end dispenser including a foam nozzle for a period of time from about 30 seconds to 10 minutes to reduce the presence of the Listeria.
2. The method of claim 1 wherein the composition is introduced daily into the drain.
3. The method of claim 2 wherein the composition is introduced into the drain for a period of two weeks.
4. The method of claim 1 wherein the drain is rinsed with water after the introduction of the composition.
5. The method of claim 4 further including the introduction of a sanitizer into the drain.
6. The method of claim 1 wherein the composition is introduced at the rate in the range of about 1.5 to 3.0 gallons per minute.
7. The method of claim 1 wherein the composition is present in the drain for a period of about 30 seconds to 10 minutes.
8. The method of claim 1 wherein the composition further includes silicates.
9. The method of claim 1 wherein the cleaning agent is present in the range of 1 wt % to 10 wt %.
10. The method of claim 1 wherein the composition is introduced into the drain without disassembly thereof.
11. The method of claim 1 , wherein the cleaning agent is present in the amount of 5 wt %.
