Babolat Star VS stuck clamps
Realize after soaking the clamp base with penetrating oils or solvents that these chemicals can and will wick into the inverted cone mechanism in the base. If this occurs you will need to remove the yellow plastic plug in the base and spray a degreaser spray into this opening to wash away dirt and cleaning solvents. Do this outside and not in a closed space.
Good Luck Dr. Frankenstein in reviving your dead machine!
