Dangers Of Using Expired Guitar Polish

One important question is the effect of using expired guitar Polish on your guitar. Because many of these polishes are made of different materials, it is hard to say the exact effects. However, one certain effect is that it is not good for the finish of the guitar. Rather than clean stains, the polish can even peel away the fine finish of the guitar or cause stains and marks that will be even more difficult to remove.

Best Practices In Using Guitar Polish

With guitar polishes, there are a bunch of guidelines surrounding how you use them. These include the best type of guitar for different finishes and the best way to use

  • Do not use silicone polishes: This is a point that is not known to most people. While silicone polish will clean most guitars just fine, it prevents any future additional finish from sticking. As you never know when the need will arise for you to change the finish of your guitar, it is best to not use silicone polishes as they can stick to parts of the guitar. If you want to change the finish of the guitar in the future, these parts will refuse to take the new finish, leading to a situation where some parts are fine while others remain as they were.
  • Do not use petrochemical polish: Some guitar polishes contain petroleum and solvents that react with nitrocellulose lacquer, hereby damaging the finish. Before you buy any guitar polish, check the container to be sure that it doesn’t contain any petroleum products. The best polishes for your guitar contain pure carnauba wax.
  • Do not spray the polish directly on the guitar: it is always advised that you should apply the polish on a soft cloth or foam made for the purpose before applying it on the guitar. This is because only a minute amount is needed on the guitar itself and using a cloth or foam to apply it is an excellent way of moderating the polish that will get on the guitar.
  • Use a soft cloth to remove dust, dirt, sweat, and oil before applying polish: Applying polish on such stains can even worsen the situation, especially with oils. Rather than the polish brightening the finish, its reaction with oil or dirt can make the stain stick to the guitar and make it harder to remove.

Following all these will ensure that you don’t get suboptimal results by using guitar polish to clean your guitar. Most importantly, remember not to use a guitar Polish that is spoiled due to it being expired.


As with every product you use, it is harmful to persist in using a guitar Polish after it has expired. While the expiry date is often far enough from the production date that you would probably be done with it before it expires, you must be wary so you won’t use an expired polish on your guitar.
