description abstract	Abstract: Although, the synthetic lubricant on Galileo slip ring bearings had been replaced with KG80 oil, the porous, phenolic ball retainer had absorbed some of the previous lubricant. Under vacuum, this residual synthetic lubricant reacted with the KG80 to form a black goo. When cleaning spaceflight components, the cleaning process must be followed by an outgassing vacuum-bake treatment-- particularly for porous materials
