A scraping device includes at least two elongated scraping members and mounting means for connecting the members to a rotating drive means, such as an electric drill, which rotates the members to accomplish scraping. The members are each provided with an off center hole and the holes of the various members are aligned with one another and a portion of the mounting means projects therethrough. Each member has a long section to one side of the hole and a short section to the other side thereof. The members are disposed with the long section of one member opposite the short section of the next adjacent member, and vice versa.
