Abstract: A dipstick wiper is provided for use in association with a dipstick of the type having an elongated blade which is proportioned to extend through an open end of an access passage of an access tube into a fluid reservoir for the purposes of determining the level of fluid in the reservoir. The dipstick wiper is in the form of a stopper for stopping the open end of the access passage of the access tube. A seat is formed in the lower end of the stopper for receiving the open end of the access tube in a close-fitting relationship to mount the stopper at the open end of the access tube in a position in which it stops the access passage. First and second through passages open through the stopper. The first through passage is proportioned to accommodate a blade of a dipstick in a close fitting sliding relationship so as to serve to wipe the blade clean when it passes therethrough.
