ABSTRACT:
A method of cleaning glass volatile contaminants from the surfaces of heat transfer fins in a fin cooler of a glass fiber forming bushing assembly is disclosed. A cleaning liquid which is a dilute alcohol solution in which the alcohol is selected from the group consisting of primary and second alcohols is sprayed in a generally flat, fan shapes spray against the side and top surfaces of the cooling fins. This spray of a dilute alcohol solution removes the contaminants from the fin surfaces while not adversely affecting the glass fiber filaments being formed during running of the bushing assembly. A solution of between 0.1 to 1.0% methanol or ethylene glycol in water has been found to be particularly satisfactory in removing boron oxide contaminants from the fin surfaces.
