Musicians are extremely wary of any substances they put on their wooden musical instruments such as guitars, violins, cellos and double basses etc. And rightly so. The biggest concerns always seem to relate to either affecting the resonant properties of the wood or causing long-term damage to the finish. It can be a bit of a minefield as the internet is so full of misinformation that many musicians resort to a 'do nothing at all' ethos.

This stems from a misunderstanding of the general function and purpose of a wax polish. Its purpose is to protect the 'finish', the lacquer, varnish, nitrocellulose or polyurethane protective layer that the luthier applies to the instrument to protect the wood for the long term. In polishing we seek to protect this finish from daily wear and tear with a thin layer of wax that acts as a kind of sacrificial layer that is easily replaced.

Most instrument makers use layers of lacquer, varnish or nitrocellulose to protect the wood of an instrument, and varnishes have been used to coat string instruments like violas, cellos and violins for hundreds of years. It started life as a closely guarded secret substance. Different formulae were concocted by the luthiers, a trade secret never to be revealed. Those varnishes were made of plant resins combined with oils like linseed, honeybee propolis, gums and other oils. The usage of beeswax was commonly added to the mix to decrease the brittleness of the resin and protect the resonant qualities of the wooden structure. This type of varnish had a higher proportion of resins, and a hard, shiny surface.

Antonio StradivariThe great violin Master, Antonio Stradivari knew these secret blends of resins, beeswax and propolis. He used them in a way that only he knew the correct proportion of each natural product creating the secret varnish formula for his high quality stringed instruments. [1]

What to look for in an instrument polish

  1. No Silicone: The reason that silicone is held in such poor esteem is that it is a colossal pain if you need to refinish a surface. A single molecule of silicone will cause a "fish-eye" in the lacquer. This is an area where the lacquer will not flow or attach. If you need to make a repair and there is silicone in an area where you want to use glue, it will act like a lubricant and give you a less than optimal joint.
  2. No Spray: Spray polishes are alcohol cleaners that contain a fair amount of water. The mist of micro-droplets get everywhere, including the unprotected fingerboard or fretboard. The alcohol will dry out the fingerboard.
  3. No Abrasives: Automotive waxes contain abrasives. You don't want to reduce the lacquer layer, you just want to add a protective layer of 100% wax. 
  4. No Oils or Petroleum Distillates: Many polishes usually contain some kind of oil. Oil can penetrate small fissures in the varnish and end up in the wood, damping the sound or making future gluing and repair more difficult. Some oil will remain on the surface and catch dirt, essentially turning your instrument into an air filter. If the oil is a vegetable base, it may harden over time, forming a new 'varnish' layer incorporating dirt from the air, perspiration and rosin (in the case of bowed instruments). This can be very difficult to remove and would require expert restoration. ‘White spirit’ or 'mineral spirit' is petroleum-based, whereas turpentine on the other hand is vegetable-based, non-hydrocarbon, most often distilled from the resin of pine trees. Naphtha is a petroleum solvent similar to mineral spirits but with a greater volatility; it is used chiefly as a paint thinner or a cleaning agent. Naphtha can also penetrate through and seep under veneer. There it will dissolve the glue, causing the veneer to loosen.
  5. Preserves Resonance Properties: Carnauba wax is very hard, being among the hardest of natural waxes. Although it creates a very deep shine, its rigidity may affect an instrument's resonance properties if not blended with softer waxes such as beeswax. Stradivari clearly understood the benefits of beeswax in preserving the flexibility of the wood.

    Can this was be used on an area of an antique violin where the varnish has worn off and the wood is exposed? Or would it seep into the pores of the wood causing build up and affecting the sound?

    Hi guys
    Please let me know what kind of your waxes are best for clarinet Grenadila dark wood? Antique gold because its for dark wood like Grenadila or pure Gold you use for violins?
    Many thanks

    Hi There, would this be suitable for the outside of drones on bagpipes? My set used to be varnished, but that what stripped off when I had them restored and refinished.

    Hi Shane, apologies for the delay in replying. Yes our beeswax polish is ideal for protecting the finish of your guitar just as it is violins. The beeswax acts as an anti-bacterial and anti-fungal sacrificial layer that is easily restored each time you polish. Don’t believe the guff you might read about ‘wax build-up’. With each fresh application of polish the old layer of wax is dissolved into the new one by the pure pine turpentine as it is being applied and as the turpentine evaporates you are left with a new single layer of protective wax.

    Hi guy’s.
    Just a quick message.
    Is it possible to use a violin varnish on a guitar, and then use the wax as a finishing off component.?
    I’m rebuilding a 59 Gibson Les Paul and I want to go with the dark violin finish.
    Any help or advice would be invaluable

    So the time has come to dust off the jar of Gilboy's Leather Balsam which has been in the cupboard for many months. 
    "Bring me back some of that shoe polish," I kept saying to Simon. 
    "It's not polish, it's a balsam," would come the correction. I refrained from asking what the difference was. For many months Simon has been excitedly coming home and telling me about the new product he has been creating and how he had finally worked out that he needed to add more lanolin in order to perfect a balsam made from the highest quality of ingredients, the purest of components and that it would revolutionise the way that people cared for their leather.

    I was rummaging around in the container just outside here. We have a large shipping container where we store all of our bits of old furniture that we use for repairs. And I stumbled across these two panels. Now look at these, two mahogany panels that are identical. I'm going to wax one and leave one. So we've got a before and after. People are always asking us about our polishes and why they're so good and why we as furniture restorers make them.
