## Abstract

A stain removal device and process sets forth a device and method which facilitates the removal of stains by employing a number of mutually beneficial structures and processes. A limited area of material is exposed to both the soap or other removal solution by encasing the limited area of material onto a washboard top surrounded by an "o" ring forming the lower portion of a sealing cap. The upper portion of the sealing cap has downward projections which both accommodate and grasp the surrounding material, but which also engage the lower portion of the sealing cap. The upper portion accommodates a downwardly directed and rotatable brush which is brought to bear on the stained area of material when the upper portion is engaged onto the lower portion of the sealing cap. The brush is rotatable to scrub the stained area of material, and has a central bore in fluid communication with the brush bristles. Once the area has been adequately scrubbed, water may be forced from a squeeze bottle onto which the lower portion of the sealing cap is mounted, through apertures in the scrub-board surface of the lower portion of the sealing cap, through the stained material, through the axial center of the brush assembly and out of the upper opening of the brush assembly.

## Claims

### Claim 1

A stain removal structure comprising:
a lower portion having a first end adapted for attachment to a squeeze bottle and a second end having at least one fluid aperture and a scrub board surface;
an upper portion positionable with respect to said lower portion, and having at least one fluid aperture extending therethrough, for the exit of fluid; and
a rotatable brush carried within said upper portion and opposing said scrub board surface of said lower portion, whereby fluid may be introduced onto said scrub board surface for scrubbing by said rotatable brush and whereby squeezing of the squeeze bottle forces the fluid introduced, as well as fresh fluid through the scrub board surface and out through said at least one fluid aperture.

### Claim 2 (depends on 1)

The stain removal structure recited in claim 1 and further comprising a squeeze bottle, connected to said lower portion and in fluid contact with said aperture of said lower portion.

### Claim 3 (depends on 1)

The stain removal structure recited in claim 1 and further comprising:
a conduit rotatably mounted with respect to said upper portion and having a first open end outside said upper portion and a second end within said upper portion and to which said brush is affixed; and
a handle, surrounding said conduit and mounted nearer said first end of said conduit, for providing manual assistance in turning said conduit.

### Claim 4 (depends on 3)

The stain removal structure recited in claim 3 wherein said conduit defines at least one conduit aperture along a section of its length within said upper portion to enable fluid to pass from within said upper portion and through said conduit.

### Claim 5 (depends on 4)

The stain removal structure recited in claim 4 wherein said brush has an back surface and a bristle surface and wherein said brush defines at least one brush aperture extending from said back surface to said bristle surface.

### Claim 6 (depends on 1)

The stain removal structure recited in claim 1 wherein upper portion further defines a plurality of finger projections extending downwardly from said upper portion to guidably engage said lower portion.

### Claim 7 (depends on 6)

The stain removal structure of claim 6 wherein each of said finger projections define an inward lip and wherein said lower portion has an under edge, and wherein said inward lip of said finger projection is sized to engage said under edge of said lower portion.

### Claim 8 (depends on 7)

The stain removal structure system of claim 7 wherein said finger projections are separated by interstitial spaces at least as wide as said finger portions.
