A small amount goes a long way, providing a very clean way to accurately condition nut slots, tuning machine gears, and saddle surfaces. KeyTone Line Guitar Lube can be applied direct from the bottle to the nut slot, with or without strings! In addition, 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! Carbon based products can stain your guitar. KeyTone Line Guitar Lube is stain free. and has the perfect viscosity for application. When applied with the applicator, you can cleanly treat tuning machine gears and nut slots without the mess. 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.

KeyTone Line Tuner Lubricant is a superior synthetic that will last indefinitely in storage, due to the pure synthetic nature.

Works great on my guitar. Keeps tuning machines lubricated and in well working order! ### ⭐⭐⭐⭐⭐ Better tuning? Yes, please! *by W***F on September 15, 2019* I wish I'd discovered this stuff decades ago! ...And I'd probably still be using the original bottle. "One drop" is probably more than I use for all six nut slots. My guitars sit out, and even so, this lasts quite a while. If I'm being lazy (or cheap?!) about changing strings, sometimes I'll put another dose on after a month or so. ### ⭐⭐⭐⭐⭐ Simple and effective *by D***N on September 7, 2024* Reworking an old guitar, the wood on the neck was drying out and trying to warp. The oil helped the wood to regain it's shape ## Frequently Bought Together - KeyTone Line Guitar Lubricant For Nut slots, Tuning Machines, String Performance - MusicNomad F-ONE Fretboard Oil Cleaner & Conditioner 2 oz (MN105) - MusicNomad MN106 TUNE-IT Lubricant, 10 mL --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/14715478-keytone-line-guitar-lubricant-for-nut-slots-tuning-machines-string](https://www.desertcart.pt/products/14715478-keytone-line-guitar-lubricant-for-nut-slots-tuning-machines-string) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-08*
