Abstract
Abstract A brush for cleaning the top surface of beverage cans has a cylindrical body member having a central longitudinal bore. A handle on a first end face of the body has a slotted portion for lifting pull tabs of beverage cans and a bottle opener. A plurality of bristles are secured on a second end face of the body, surrounding the longitudinal bore in a circular pattern. A cylindrical sleeve is received for longitudinal sliding movement around the body for selective engagement around the top portion of a beverage can. The sleeve serves as a guide to assist in proper positioning of the brush. A detent is provided for retaining the sleeve in an extended position.
