## Abstract

A tool with two sets of cleaning elements disposed at first and second radii about a common axis thus providing cleaning surfaces for all the spaces between a blender blade on a stepped shaft and its supporting base. Depending on the size of the step the cleaning elements are either vertical blades or nodules in the edge of a planar body.

## Claims

### Claim 1

A tool for cleaning a blender blade assembly with a stepped shaft, the tool comprising a handle and a head with a first set of cleaning elements disposed at a first height and in a semi-circle at a first radius about a common axis, and a second set of cleaning elements disposed at a second height and in a semi-circle at a second radius about the common axis, wherein the head comprises a pair of rigid arms holding the first set of cleaning elements and the second set of cleaning elements, and wherein the first set of cleaning elements is arranged in a first plane and the second set of cleaning elements is arranged in a second plane, and the second plane is different from the first plane.

### Claim 2 (depends on 1)

The tool as in claim 1, wherein the first set of cleaning elements comprise vertical blades.

### Claim 3 (depends on 2)

The tool as in claim 2, wherein the second set of cleaning elements comprise nodules formed on an edge of a planar body.

### Claim 4 (depends on 2)

The tool as in claim 2, wherein the second set of cleaning elements comprise vertical blades.

### Claim 5 (depends on 1)

The tool as in claim 1, wherein the first set of cleaning elements and the second set of cleaning elements are formed from a resilient material.

### Claim 6 (depends on 1)

The tool as in claim 1 wherein cleaning elements of the first set of cleaning elements and cleaning elements of the second set of cleaning elements are all directed towards the common axis.

### Claim 7 (depends on 1)

The tool as in claim 1, wherein the first set of cleaning elements is radially spaced a distance outwardly away from the second set of cleaning elements.
