Abstract

The present invention provides a method of manufacturing and distributing a cleaning solution for use in a vehicle washing facility. The method includes receiving pre-measured raw chemical material at a distributor'"'"'s facility, diluting the pre-measured raw chemical material using a mixing apparatus at the distributor'"'"'s facility to form a cleaning solution, packaging at least a portion of the cleaning solution into containers at the distributor'"'"'s facility, and delivering at least one of the containers from the distributor'"'"'s facility directly to the vehicle washing facility.

Claims

1. A method of diluting pre-measured raw chemical material, the method comprising:

at least partially filling a tank with a diluent;

pumping the pre-measured raw chemical material from a first container into the tank via a passageway;

rinsing the first container with diluent to form a rinse solution having a residual amount of raw chemical material;

pumping the rinse solution from the first container into the tank via the passageway to rinse the passageway; and

pumping the diluted raw chemical material from the tank to a second container via the passageway.

2. The method of claim 1, wherein pumping the diluted raw chemical material from the tank includes pumping the diluted raw chemical material to the second container having a smaller volume than the tank.

3. The method of claim 1, further comprising:

controlling a first pump to pump the pre-measured raw chemical material from the first container to the tank; and

controlling a second pump to pump the diluted raw chemical material from the tank to the second container.

4. The method of claim 3, wherein a controller interfaces with the first and second pumps and a computer, and wherein the method further includes inputting a mixing code into the computer to allow operation of the first and second pumps.

5. The method of claim 1, further comprising delivering the second container to a vehicle washing facility.

6. The method of claim 1, further comprising providing a mixing apparatus at the distributor'"'"'s facility, the mixing apparatus including:

a tank selectively fluidly connectable to a source of pressurized diluent by a passageway;

a first pump selectively fluidly connectable to the passageway, the first pump adapted to pump the pre-measured raw chemical material from the first container through the passageway to the tank to mix with the diluent in the tank; and

a second pump selectively fluidly connectable to the passageway, the second pump adapted to pump the diluted raw chemical material from the tank through the passageway to the second container.

7. The method of claim 1, further comprising disposing of the first container without additional rinsing.

8. The method of claim 1, further comprising spilling the pre-measured raw chemical material into the tank.

9. The method of claim 8, wherein spilling the pre-measured raw chemical material into the tank includes spilling particulate raw chemical material into the tank.

10. The method of claim 1, further comprising providing a third container and an inverter moving the third container between a lowered position, in which the pre-measured raw chemical material is loaded into the third container, and a substantially inverted position, in which the pre-measured raw chemical material spills out of the third container and into the tank.
