Abstract

There is provided a system and method of cleaning surfaces of an interior cabin space of a contamination comprising a microbial and viral load. The method includes the steps of sealing the interior cabin space and placing water, and a solid or gel pack, into a container and generating a vortex the container by rotating an impeller. The agitation causes the solid or gel pack to release a gaseous cleaning agent. An air-borne spray exiting from the container spreads throughout the interior cabin space to coat the surfaces to be cleaned within the interior cabin space. The cabin is maintained closed for an effective time period while the coating from the air-borne spray dwells on the surfaces to eliminate or substantially reduce the load of the contamination.

Claims

1. A method for cleaning a cabin interior of a car, truck, SUV or tractor-trailer rig of a microbial or viral contamination, the system comprising:

sealing the cabin of a car, truck, SUV or tractor-trailer rig from the outside environment and starting an air recirculation system of the cabin;

placing a portable apparatus inside the sealed cabin interior, the apparatus comprising;

a container having therein water with a solid or a gel pak that releases a gaseous cleaning agent upward and out of the container; and

maintaining the cabin closed while allowing the gaseous cleaning agent to dwell for an effective time in the sealed cabin interior to reduce a microbial and viral load on interior surfaces within the sealed cabin.

2. The method of claim 1, wherein the apparatus is sized to fit inside a cup-holder inside the cabin.

3. The method of claim 1, wherein the apparatus includes a detector and indicator to indicate when a concentration of the gaseous cleaning agent has reduced to a safe level.

4. The method of claim 1, wherein the apparatus includes a motor and a step of activating the motor of the apparatus is carried out remotely.

5. The method of claim 1, wherein the effective time is in the range from about 10 to about 30 minutes.

6. The method of claim 1, wherein the effective time to reduce a microbial and viral load on interior surfaces further includes removing odors from the cabin interior.

7. The method of claim 1, wherein cabin is maintained closed for up to about 8 hours.

8. The method of claim 1, wherein the container includes therein an impeller driven by a motor.

9. A method for cleaning a cabin interior of a car, truck, SUV or tractor-trailer rig of a microbial or viral contamination, the system comprising:

sealing the cabin of a car, truck, SUV or tractor-trailer rig from the outside environment and starting an air recirculation system of the cabin;

placing a portable apparatus inside the sealed cabin interior, the apparatus comprising;

a container having therein water with a solid or a gel pak that releases a gaseous cleaning agent comprising chlorine dioxide upward and out of the container; and

maintaining the cabin closed while allowing the gaseous cleaning agent to dwell for an effective time in the sealed cabin interior to reduce a microbial and viral load on interior surfaces within the sealed cabin.

10. The method of claim 9, wherein the apparatus is sized to fit inside a cup-holder inside the cabin.

11. The method of claim 9, wherein the apparatus includes a detector and indicator to indicate when a concentration of the gaseous cleaning agent has reduced to a safe level.

12. The method of claim 9, wherein the apparatus includes a motor and a step of activating the motor of the apparatus is carried out remotely.

13. The method of claim 9, wherein the effective time is in the range from about 10 to about 30 minutes.

14. The method of claim 9, wherein the container includes therein an impeller driven by a motor.
