KeyTone Line Guitar Lubricant Script.jpg

KeyTone Line Guitar Lubricant provides a superior treatment for a guitar’s friction issues. Excellent for Tuning Machines, nut slots and saddles surfaces. A small amount goes a long way, providing a very clean way to accurate conditioning of your instrument.

The enclosed Archival cotton applicators allow you to apply the KeyTone Lubricant exactly were you need it! The Teflon-like micro-beads actually fill surface irregularities of mating parts. This forms a smooth lubricated surface with minimal application.

Liquid oils and sprays get into unwanted places! KeyTone Line Guitar Lube has the perfect viscosity for application. When applied with the applicator, you can cleanly treat surfaces without the mess. KeyTone Lube will not stain like Carbon products.

Because KeyTone Line lubricant is pure synthetic, it provides very stable and predictable properties. Petroleum based machine and gear oils are made from refined crude oil and contain impurities. These impurities interfere with film strength and wear protection. They are prone to forming deposits. In addition, many popular natural oils turn rancid over time.

KeyTone Line Guitar Lubricant is a superior synthetic that will last indefinitely in storage, due to the pure synthetic nature. It is thinned temporarily with a special solvent carrier that evaporates, leaving a thin coating that provides long lasting lubrication and corrosion protection. The food grade lubricant is odorless and comes in a sealed polypropylene applicator.


Kit includes 6 applicators and enough special viscosity lubricant for approximately 40 treatments. Manufactured in the USA, with a full guarantee of performance.
