Countering Myths and Faulty Information

  • Can you use lemon oil on your guitar? Pure lemon oil contains citric acid which is good for cleaning. Citric acid can be detrimental to adhesive used for a nut, binding, and frets. The guitar assembly website states, “…pure lemon oil should definitely not be used on your guitar fretboard under any circumstances. It is much too strong and can dry the fretboard out over the long-term.”1 Lemon oil products for wood are blended with elements such as olive oil, vinegar, etc. A blended product minimizes the concentration of citrci acid, however; products rarely show the amount of lemon oil in their products.
  • Can you use mineral oil on your guitar? Generally speaking, it is safe to use mineral oil on your guitar fretboard for conditioning. A drawback is that pure mineral oil does not facilitate any level of cleaning.
  • Can you use culinary oil on your guitar? While it may be tempting to go to your kitchen and grab vegetable oil, peanut oil, coconut oil, or similar cooking oil, don’t do it. Once applied, these oils begin to break-down and can later have foul greasy kitchen smell. Additionally, per the Rock Guitar Universe website, “You must NOT use coconut oil, olive oil, lemon oil or vinegar on your guitar either the strings, fretboard or any other part. all of these products can cause unrecoverable damage to the wood of your guitar because they are acidic.”2
  • Can you use household cleaners on your guitar? To answer this question we defer to the smart advice by the experts at Premier Guitar. An excerpt from a recent article states, “No matter what brand or type of cleaner you choose, always avoid those that contain silicone, heavy waxes, lacquer thinner, bleach, etc. Household furniture polish and all-purpose cleaners—such as Pine Sol, Windex, and 409—will also damage your finish.”3

A word of caution from Martin Guitars; Per the Martin Guitars website, “Martin Guitar does not recommend using lemon oil on the fingerboard. The acids in lemon oil break down the finish of your guitar. It may also speed the corrosion of the frets and decrease the life of your strings.”4
