An apparatus for removing residual material from a cylindrical container which comprises:

• A. moving means for supporting and rotating said container, said moving means comprising:
• 1. a base having an upper surface;
• 2. a pair of substantially parallel shafts rotatably coupled to said base above said upper surface;
• 3. at least two support wheels of substantially the same diameter rigidly attached to each of said shafts in a wheel-and-axle relationship, said shafts, support wheels, and base being situated so as to enable support of said container at its exterior curved surface on the outer perimeter of said support wheels;
• 4. at least one driven wheel rigidly attached to each of said shafts in a wheel-and-axle relationship;
• 5. an elongated frame attached to said base and extending above said upper surface of said base;
• 6. a rotational driving means coupled to said frame;
• 7. a driving wheel rotatably coupled to said driving means;
• and
• 8. a closed loop flexible tensile member engaged with the outer perimeters of said driving wheel and said driven wheels of each of said shafts so as to effect rotation of said driven wheels of each of said shafts in the same direction which in turn effects rotation of said support wheels via said respective shafts to effect rotation of said container when resting on said support wheels;
• and
• B. a tank means having a bottom surface on which said moving means is rested, said bottom surface being adapted to accomodate said moving means with said container supported on said moving means, said tank means being capable of containing solvent to a sufficient depth to submerge at least a portion of said container when supported on said moving means and to effect contact of said residual material with said solvent.
