Abstract
Method of cleaning sucker rods using a portable cleaning tool containing a rotating brush assembly to remove scale and corrosion residue on the sucker rods is described herein. The brush is annular with an empty or hollow center, such that the rod can penetrate through the hole in the brush. The tool is powered by air compression, and also contains a mechanism of removing the collected debris for disposal. The cleaning tool assembly could be either a standalone device on site placed on a mounted rack, or could be attached to the rod to be cleaned.
