## Abstract

In a cleaning device, in particular for the interdental area, comprising two twisted, wire-type sections (1, 2), it is provided, with a view to putting into practice novel cleaning methods, the cleaning being accompanied by the application of care and cleaning agents, that the wire-type sections (1, 2) are twisted in such a way that at least one free loop or eye (9) is formed.

## Claims

### Claim 1

A cleaning device for use in an interdental area, said cleaning device having a holding member and radially extending fibers inserted in between two twisted wire-type sections (1, 2) to form a brush, a first end of said two twisted wire-type sections being engaged in said holding member, said cleaning device comprising at least one open loop or eye formed at a free second end of the two twisted wire-type sections, said two twisted wire-type sections consisting of at least one plastic fiber and being formed from a bow bent in the shape of a U, the open loop or eye being formed in a vicinity of a bight of the U, said radially extending fibers containing an abrasive additive selected from the group consisting of silicon carbides and aluminum oxide.

### Claim 2 (depends on 1)

The cleaning device according to claim 1, wherein the loop or eye is triangular.

### Claim 3 (depends on 1)

The cleaning device according to claim 1, wherein the loop or eye is rhomboidal.

### Claim 4 (depends on 1)

The cleaning device according to claim 1, wherein the holding member can be inserted into an oscillating appliance.

### Claim 5

A cleaning device for use in the interdental area, said cleaning device having a holding member, said cleaning device comprising two wire sections formed from a plastic fiber bow bent in the shape of a U, an elongated open loop being formed in a vicinity of a bight of the U at the free first end of said two wire sections,
an insertion portion formed by twisting a second end of said two wire sections together, said elongated loop extending to said insertion portion,
a holding member,
said insertion portion engaged in said holding member up to said elongated loop,
wherein said holding member can be inserted into an oscillating appliance for use in cleaning the interdental area.
