Abstract
There is provided in a preferred embodiment of the present invention a maintenance device for snaps or fasteners having a housing and a dynamic body that is slidably engaged within said housing. Attached to the dynamic body is a pair of cleaning arms. A spring positioned between the body and the housing biases the body and arms to a relaxed and extended position. When the body is pressed against and engages a fastener, the body moves to a retracted position within the housing causing the cleaning arms pivot and engage the fastener. With the cleaning arms engaged, a twisting movement of the housing removes corrosion, dirt and debris from the fastener. The device further includes a refillable lubrication reservoir and channel which serves to lubricate the fastener while it is cleaned.
