Paul Michener invented Grease Buster Tools and makes the toughest tools on the market for dealing with plugged grease fittings from his home in Waynesville, Ohio.

The Shop Size Grease Buster is the most rugged version of his products, fit for heavy use and compatible with the pneumatic piston.

The Grease Buster’s piston, included with the product, is hollow and should be filled with a liquid (not aerosol) penetrating oil. Seat the piston in the Grease Buster, attach the coupler to your Zerk fitting, and tap the piston with a hammer. This forces the penetrating oil into the fitting and loosens it for regular greasing.

For customers with a pneumatic hammer, they might prefer using the pneumatic piston (sold separately) instead of the standard piston. Note that the pneumatic piston is only compatible with the Shop Sized model, not the Regular Size version.



The Grease Buster is the answer to a problem that many people have lived with for a long time. Plugged up grease fittings and bearings are a problem common in machinery. One greases a machine and the grease can dry out before the machine is used again. The tool consists of a heavy-duty adjustable hydraulic coupler, cylinder and a piston with a knob.

Instructions: Remove the piston. Fill the cylinder by pouring in a penetrating oil. Start the piston back into the cylinder. Place the tool onto the grease fitting and by tapping the piston, forcing the solvent into the fitting and or bearing. The key work is TAP. Using a lightweight hammer and small, rapid taps, work the penetrating oil into the fitting. You’re trying to dissolve the clog, not blast it out of the way. Repeat if necessary.
