Disclosed is the use of clean xerographic carrier having high tribo-electrification to remove toner residue from reclaimed toner bottles. When toner bottles are empty it is desirable to reuse them. Removing the last remaining amount of toner from the bottles is difficult. The bottles are typically washed and dried, but they may become contaminated by residual soap films. To overcome this problem, a small amount of clean carrier poured into an empty bottle and shaken around removes the toner from the interior bottle surface. Triboelectric forces between the carrier and the toner cause the toner to adhere to the carrier. Thereafter, both are emptied from the bottle by pouring the material out. The toner can then be removed from the carrier by a source of high air pressure so that the carrier can be used again for cleaning.
