Sounds like a "Bon-Ami" treatment to me. Probably a fine abrassive compound in pelet form. We did the "B-A" treatment to an old Co-op tractor as an experiment at the dealership I worked at in the 70's. We put the tractor on the dyno and it pulled about 15HP, did the "treatment", by letting the dust get sucked in at the carb while it was on the dyno, and lo and behold, the HP slowly came up to 25HP, which was close to the PTO rating. (We did this experiment as we overhauled it later.) Now the down side; The abrassive migrated into the oil system, and lo and behold the oil pressure began to drop. When we OH'd, the bearings showed the scoring of abrassive, and the cylinders did show a roughing of the old glazing, and the rings were "sharpened", thus better sealing and oil control. But you could see it would be a very short term fix, and with the lower oil pressure, and "fines" in the oil, a more catastrophic development could take place. Just my .02
