## Abstract

A self-adhering cleaning block is disclosed. In some embodiments, the self-adhering cleaning block includes a first surface, a second surface opposite the first surface, and a handle extending out from a part of the second surface, where the material composition of the block may be essentially uniform, and where the material composition of the block may further comprise a non-ionic surfactant and a liquid component. In addition, a cleaning article including a self-adhering cleaning block is disclosed. Moreover, a method is disclosed. In certain examples the method comprises mixing a non-ionic surfactant and a liquid component to form an essentially uniform cleaning composition, and then extruding, pressing or casting the cleaning composition to form a cleaning block having a first surface, a second surface opposite the first surface, and a handle extending out from a part of the second surface.

## Claims

### Claim 1

A cleaning article comprising:
a self-adhering cleaning block, the cleaning block comprising:
a first surface;
a second surface opposite the first surface; and
a handle integrally formed with and extending out from a part of the second surface;
the first surface, second surface, and handle forming a unitary structure having an uniform material composition, wherein the material composition of the block comprises:
a non-ionic surfactant; and
a liquid component.

### Claim 2 (depends on 1)

The cleaning article of claim 1, wherein the block is extruded, pressed, or cast into a final shape having the first surface, the second surface, and the handle.

### Claim 3 (depends on 1)

The cleaning article of claim 1, wherein the handle has a handle height measured between a portion of the second surface adjacent to the handle and a top portion of the handle, and wherein the handle height is about 0.20 inches or more.

### Claim 4 (depends on 1)

The cleaning article of claim 1, wherein the cleaning block has a block height measured between a bottom portion of the first surface and a top portion of the handle, wherein the cleaning block has a block width measured between a first side of the block and a second side of the block, and wherein the ratio of the block height to block width is between about 1:4 and about 4:1.

### Claim 5 (depends on 1)

The cleaning article of claim 1, wherein the block height is about 0.20 inches or more.

### Claim 6 (depends on 1)

The cleaning article of claim 1, wherein the cleaning block further comprises a plurality of projections extending out of the first surface.

### Claim 7 (depends on 1)

The cleaning article of claim 1, further comprising a barrier layer covering at least a portion of the handle of the cleaning block.

### Claim 8 (depends on 7)

The cleaning article of claim 7, wherein the barrier layer is releasably adhered to the at least a portion of the handle, such that a user may remove the barrier layer after applying the self-adhering cleaning block to a surface to be cleaned.

### Claim 9 (depends on 7)

The cleaning article of claim 7, wherein the barrier layer comprises one or more water soluble materials.

### Claim 10 (depends on 1)

The cleaning article of claim 1, wherein the material composition of the block further comprises a solid anionic surfactant.

### Claim 11

A cleaning article comprising:
a self-adhering cleaning block, the cleaning block comprising:
a block body having a first surface and a second surface opposite the first surface;
a handle integrally formed with and extending out from a part of the second surface;
the block body and the handle having the same material composition, wherein the material composition of the block body and the handle comprises:
a non-ionic surfactant; and
a liquid component.

### Claim 12 (depends on 11)

The cleaning article of claim 11, wherein the block body and the handle are extruded, pressed, or cast together into a final shape.

### Claim 13 (depends on 11)

The cleaning article of claim 11, wherein the cleaning block further comprises a plurality of projections extending out of the first surface.

### Claim 14 (depends on 11)

The cleaning article of claim 11, wherein the material composition of the block body and the handle further comprises a solid anionic surfactant.
