27. The method of any one of claims 32 to 35, wherein step (d) comprises contacting the proximal end of the, or each, cleaning element with the resilient material.

28. The method of claim 27, wherein step (d) comprises fixing the resilient material to the proximal end of the, or each, cleaning element.

29. The method of any one of claims 17 to 28, comprising fixing the resilient material to the head portion of the body.

30. The method of any one of claims 17 to 29, comprising defining part of an exterior surface of the implement with the resilient material.
