The Grease Joint Rejuvenator opens clogged
grease joints and fittings effortlessly in less than a minute. Loosens dried
grease in joints with just a tap. Just fill the tool with mineral spirits,
attach it to the clogged grease fitting and tap it with a mallet. The mineral
spirits will be forced into the grease fitting under pressure to instantly
dissolve dried grease. The mineral spirits will then later completely evaporate
leaving no residue. Works great!
