Claim:
An apparatus for applying liquid to a person's back comprising: a. a vertical frame capable of attachment to a vertical surface and having a backing portion facing an outer framing portion, wherein a tooth guide having repeated rectangular indentations is attached to the outer framing portion such that it faces the backing portion directly and is spaced apart from the backing portion so as to maintain a channel between the backing portion and the tooth guide; b. an inner rectangular frame fit into and capable of being lifted within the channel of the vertical frame, and further comprising a rotary disk comprised of a flat surface and teeth regularly arrayed around the circumference of the disk, where said disk is vertically mounted to a bottom portion of the inner frame such that the flat surface is directed toward the person's back and that when the inner frame is lifted, the disk teeth will sequentially engage the rectangular indentation of the tooth guide so that the disk rotates; and c. an absorbent pad attached to the flat surface of the disk which releases absorbed liquid when pressure is applied thereto.
