We recommend cleaning the Original Uni-Loc® Quick Release joint when you first receive your cue and every six months thereafter. These joints are precision manufactured to exact tolerances and even a modest amount of dirt can create a problem. You can use a Q-Tip dipped in Isopropyl alcohol to clean the inside threads and bore of the shaft insert. Clean the joint pin and threads with alcohol and a clean rag. We recommend the use of joint protectors to help keep your joint clean and to protect it from damage.
