Fret Doctor® Doctor Lubricus

With this advanced super lubricant, you can eliminate the damage on your instrument that would occur due to contact friction, as well as improve string lifetimes and tuning stability.

There are many places where bone, plastic, wood, or metal come into contact. Vibrations from playing will slowly, and sometimes quickly, remove material. Just a small amount in the nut grooves or tuner gears and tremolo parts- including on spring mounts and bridge saddles- will eliminate this wear. 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, allowing the screw to flex with the wood.

Through years of using it in our repair shop, we have not noticed any adverse effects such as finish, wood, or metal discoloration. Besides using it for instruments, it works great on zippers, hinges, and sticky case or door locks!

Available in a .5ml syringe or 1 oz syringe (shop size) for precision injection, as well as a .75oz tube for larger application areas.
