When triple valves are cleaned with kerosene it is impos-sible to completely remove the kerosene from the sliding .■surfaces to which dry graphite lubricant is to be result is a tendency for the graphite to cake between thevalves and their seats, sufficiently pronounced at times tocause improper operation of the valves.

With the old method of cleaning considerable hammeringand working of the piston rings in the grooves was necessaryin order to loosen them and many rings were broken or bentin the process. The soda solution thoroughly cleans thegrooves and leaves the rings free. This in itself effects aconsiderable saving both of time and material.
