A tube cleaning device having a pair of jaws pivotally mounted on a frame and having opposed abrading surfaces defining an abrasion cavity, a mandrel fixed to the frame and extending axially thru the cavity for slidably receiving a tube end to be cleaned, spring structure forcing the abrading surfaces toward each other and laterally toward the mandrel, and a rotator knob on the frame for rotating the device in either direction around a tube end positioned on the mandrel.
