配方說明：	Boiler Scale Removal

配制方法：	Where boiler scale is siliceous in character, ammonium bifluoride is used with inhibited hydrochloric acid for its removal. Two percent (2%) or less in 15% inhibited hydrochloric acid at elevated temperatures is left in contact with the scale long enough to loosen it so that it may be flushed from the tubes.
