Advanced super lubricant.
When you find yourself in a sticky situation. Doctor Lubricus can slip on through.
Lube your nuts.
Just a small amount in the nut groves, tuner gears, tremolo parts including spring mounts and bridge saddles will help to eliminate friction. When installing a wood screw, such as for strap buttons or trem mounts, apply a small amount onto the screw before installing in a pre drilled hole.
While using it in our repair shop, we have not noticed any adverse effects such as finish, wood, or metal discoloration but you may want to test a small amount yourself in an inconspicuous place.
Beside using it for guitars, it also works great on zippers, hinges, and sticky case or door locks!
