  • Patent number: 4010512
    Abstract: A dip stick cleaning tool having a cylindrical body with flexible sides and removable ends. The body contains a core of absorbant, flame proofed, rolled material having an open center for receiving the dip stick. The top of the tool has an opening leading into the open center of the core and also has a pivotably mounted cover that acts with the side of the top opening to clean an inserted dip stick with squeegee action while the core wipes the dip stick and absorbs the wiped liquid. Inside the cylindrical body the core is spaced from the cylinder walls by a plurality of ribs to allow air to circulate around the core, and the core is spaced from the top of the tool by a plurality of pointed spurs to provide a space to hold liquid squeezed out of the core when the cylindrical body is squeezed while operating the tool.
