Abstract

A substantially self-contained system and corresponding method provides practical spot cleaning of soiled garments without requiring the use of chlorinated solvents. A soiled garment may optionally be pretreated with either of a water based or petroleum based nonchlorinated cleaner. Thereafter, a relatively high level of vacuum force is applied to the soiled garment to be cleaned, and comprises the flushing agent for both the soil and the pretreatment cleaner. Drying effects obtained with the vacuum force may be augmented by the addition of compressed air directed onto the garment. A self-contained workstation practicing such methodology may optionally include an electric water boiler for generating steam to be applied as a supplement to vacuum and also include an industrial grade vacuum pick-up with a waste collector for generating the relatively high vacuum force, preferably at least about 80 inches of mercury of static pressure.

Claims

1. A method of commercially spot cleaning soiled garments without the use of chlorinated solvents, said method comprising:

pretreating spots on the soiled garment to be cleaned by the application of nonchlorinated cleaners thereto; and

applying a relatively high vacuum force to the pretreated spots so as to flush both soil and pretreatment cleaner therefrom and for drying the garment being cleaned;

further including providing a substantially self-contained workstation having an upper work surface on which a user may work a soiled garment to be cleaned for pretreating same, a self-contained vacuum means for generating said relatively high vacuum force, a stand-up vacuum arm connected to said vacuum means and adapted for receiving a soiled garment thereon, and vacuum waste collector means carried on said workstation and associated with said vacuum means for collecting waste materials vacuumed through said vacuum arm under said vacuum force; and

further including providing said substantially self-contained workstation with a self-contained steam generator means and associated steam spray gun and interconnecting hose for selectively applying steam to the soiled garment.

2. A method as in claim 1, wherein said relatively high vacuum force is at least about 80 inches of mercury of static pressure.

3. A method as in claim 2, wherein said non-chlorinated cleaner is petroleum based.

4. A method as in claim 3, further including:

providing an air compressor and air gun carried on said workstation for selectively applying compressed air to the garment for enhanced drying thereof;

providing means for holding additional water, associated with said workstation, for replenishing water to said steam generator means; and

providing said workstation with adjustable legs for leveling said upper work surface thereof, a sink built into said upper work surface, and a splashback panel adjacent said upper work surface.

5. A method as in claim 1, wherein said nonchlorinated cleaner is petroleum based.

6. A method as in claim 5, further including providing an air compressor and air gun carried on said workstation for selectively applying compressed air to the garment for enhanced drying thereof.

7. A method as in claim 6, further including:

providing means for holding additional water, associated with said workstation, for replenishing water to said steam generator means; and

providing said workstation with adjustable legs for leveling said upper work surface thereof, a sink built into said upper work surface, and a splashback panel adjacent said upper work surface.

8. A method as in claim 7, wherein said relatively high vacuum force is at least about 80 inches of mercury of static pressure.

9. A method as in claim 1, further including providing an air compressor and air gun carried on said workstation for selectively applying compressed air to the garment for enhanced drying thereof.

10. A method as in claim 1, further including providing means for holding additional water, associated with said workstation, for replenishing water to said steam generator means.

11. A method as in claim 1, further including providing said workstation with adjustable legs for leveling said upper work surface thereof, a sink built into said upper work surface, and a splashback panel adjacent said upper work surface.

12. A system for commercially spot cleaning soiled garments without the use of chlorinated solvents, said system comprising:

a user workstation;

means for pretreating spots on the soiled garment to be cleaned by the application of nonchlorinated cleaners thereto; and

vacuum means for selectively applying a relatively high vacuum force to the pretreated spots, so as to flush both soil and pretreatment cleaner therefrom as such garment is drying with said vacuum force;

wherein said workstation includes a substantially self-contained workstation having an upper work surface on which a user may work a soiled garment to be cleaned for pretreating same, a self-contained vacuum means for generating said relatively high vacuum force, a stand-up vacuum arm connected to said vacuum means and adapted for receiving a soiled garment thereon, and vacuum waste collector means carried on said workstation and associated with said vacuum means for collecting waste materials vacuumed through said vacuum arm under said vacuum force; and

means for spraying steam including a self-contained steam generator means and associated steam spray gun and interconnecting hose for spraying said steam on the soiled garment.

13. A system as in claim 12, wherein said relatively high vacuum force is at least about 80 inches of mercury of static pressure.

14. A system as in claim 13, wherein said non-chlorinated cleaner is petroleum based.

15. A system as in claim 14, further including:

an air compressor and air gun carried on said workstation for selectively applying compressed air to the garment for enhanced drying thereof; and

means for holding additional water, associated with said workstation, for replenishing water to said steam generator means;

wherein said workstation further includes adjustable legs for leveling of said upper work surface thereof, a sink built into said upper work surface, and a splashback panel adjacent said upper work surface; and

said system further including means for adjusting the position of said vacuum arm to facilitate access thereto by a system user.

16. A system as in claim 12, wherein said nonchlorinated cleaner is petroleum based.

17. A system as in claim 16, further including an air compressor and air gun carried on said workstation for selectively applying compressed air to the garment for enhanced drying thereof.

18. A system as in claim 17, further including:

means for holding additional water, associated with said workstation, for replenishing water to said steam generator means; and

wherein said workstation further includes adjustable legs for leveling of said upper work surface thereof, a sink built into said upper work surface, and a splashback panel adjacent said upper work surface.

19. A system as in claim 18, further including:

means for adjusting the position of said vacuum arm to facilitate access thereto by a system user; and

wherein said relatively high vacuum force is at least about 80 inches of mercury of static pressure.

20. A system as in claim 12, further including an air compressor and air gun carried on said workstation for selectively applying compressed air to the garment for enhanced drying thereof.

21. A system as in claim 12, further including means for holding additional water, associated with said workstation, for replenishing water to said steam generator means.

22. A system as in claim 12, wherein said workstation further includes adjustable legs for leveling of said upper work surface thereof, a sink built into said upper work surface, and a splashback panel adjacent said upper work surface.

23. A system as in claim 12, further including means for adjusting the position of said vacuum arm to facilitate access thereto by a system user.
