A slim brush on a long handle, made for the containers a hand cannot get into. It reaches the bottom of a vacuum flask, the shoulder of a teapot and the base of a tall tumbler, which is where residue and old tea tannin quietly build up.
The shaft flexes as it turns, so the head follows the curve of a narrow neck instead of fighting against it, and the bristles keep contact with the wall the whole way down. That flexibility is what lets one brush cover a whole shelf of different shapes.
Use it on insulated bottles, jugs, carafes, blender beakers and travel mugs, with warm water and a drop of washing-up liquid. Rinse the head thoroughly afterwards and hang the handle so the bristles dry out rather than sitting damp in a drawer. One brush is supplied.
