Care & Cleaning

Storage
A guitar or mandolin should be kept at an air humidity level of between 40% and 60% and not be exposed to sudden or big changes in air humidity and/or temperature. Here are some additional tips:

  • Keep your instrument in its case or gig bag when you're not playing it. This also protects the instrument from external damage.
  • Keep your instrument away from anything that strongly affects air humidity, and temperature, such as heaters, air conditioning vents, windows, etc.
  • Give your instrument time to acclimate itself to a room inside its case before taking it out to play.

Prolonged exposure to low air humidity levels can cause lower action, fret buzzing, sharp fret ends, lacquer checking, or even wood cracks. If you live in a dry climate, you should consider purchasing a room humidifier to use in the room where you store your instruments. If the air becomes too dry, the instrument should be kept in its case with an in-case air humidifier. This should be refilled regularly.
Prolonged exposure to high air humidity levels and temperature can cause higher action, warped back and sides and possible cracks in the lacquer finishing. It could also weaken joints with water-based glues.

Cleaning and Maintenance
Lacquer, wood and metal are all affected by sweat, so clean your instrument regularly.

  • Clean the neck and body with a warm, damp (not wet) cloth, and remove remaining moisture with a clean dry cloth. Don't use any household chemical cleaning agents.
  • In the same way, you can clean the strings after use.
  • Once in a while, after cleaning the fingerboard, apply a little oil to it with a piece of cloth. After a few minutes, remove excess oil with a clean, dry cloth.


Action & Truss Rod & Playability
Every Eastman gets a custom set up before it leaves our workshop. We choose the strings and action that we believe achieve the best sound and playability. However, your playing style might require a different string gauge. Switching to another gauge will affect the action of the instrument and the neck curve. If you want any adjustment made, we advise you to have this done by an experienced guitar technician. Your Eastman dealer can help you with this.
