Store your guitar in a hard case or padded gig bag in a climate-controlled room
A guitar left in the wrong conditions will warp, crack, or go out of tune within weeks. The best storage is a hard case — the kind with a rigid shell that protects against bumps and pressure — kept in a room where the temperature stays between 65 and 75 degrees Fahrenheit and humidity stays between 40 and 50 percent. If a hard case is not an option, a padded gig bag works for shorter storage periods, but it offers less protection against temperature swings and physical damage.
The room itself matters as much as the case. Avoid attics, basements, garages, and windowsills. Attics and garages heat up and cool down wildly, which causes the wood to expand and contract. Basements stay damp. Windowsills get direct sunlight, which fades the finish and dries out the wood. A bedroom closet, a climate-controlled storage unit, or a living room corner away from heating vents and air conditioners is ideal.
Key Takeaways
- Store your guitar in a hard case or padded gig bag inside a room where temperature stays between 65 and 75 degrees and humidity stays between 40 and 50 percent.
- Avoid attics, basements, garages, and direct sunlight, which cause the wood to warp, crack, or dry out.
- Loosen the strings slightly if you are storing the guitar for more than a month, but do not remove them entirely.
- Check the guitar every two weeks for signs of warping, cracks, or rust on the tuning pegs and bridge.
- A room humidifier or dehumidifier may be necessary if your home is very dry or very damp.
Prepare the guitar before closing the case
Before you put the guitar away, loosen the strings by turning each tuning peg counterclockwise until the strings are slack but not completely loose. This reduces the tension pulling on the neck and headstock, which is especially important if you are storing the guitar for more than a month. Do not remove the strings entirely — they protect the neck from warping and help the guitar hold its shape.
Wipe down the body, neck, and fretboard with a soft, dry cloth to remove dust, sweat, and oils. If the fretboard is very dry, you can explore a small amount of lemon oil or fretboard conditioner, but use it sparingly — too much oil traps moisture and causes swelling. Let any oil dry completely before closing the case.
Check the tuning pegs, bridge, and strap buttons for any loose hardware. Tighten anything that moves by hand, using the correct screwdriver or wrench. Loose hardware can rattle inside the case and damage the finish.
Position the guitar correctly inside the case
Lay the guitar flat in the case with the headstock pointing toward the narrower end. The neck should rest on the padded support without any pressure on the tuning pegs. If the case has a neck rest or foam insert, use it — it keeps the headstock from rolling or shifting during storage.
Fill any empty space in the case with soft cloth or bubble wrap so the guitar cannot slide around. Do not pack it so tightly that you have to force the lid closed — excessive pressure can bend the neck or crack the body. The guitar should sit snugly but with no strain.
If you are using a gig bag instead of a hard case, follow the same positioning: headstock first, neck supported, and no pressure on the tuning pegs. Gig bags compress more easily than hard cases, so check that the guitar is not being squeezed by the padding.
Monitor temperature and humidity in your storage space
Temperature swings cause the wood to expand and contract, which leads to cracks and warping. Humidity swings cause the wood to swell and shrink, which can separate the glued joints and warp the neck. The ideal range is 40 to 50 percent humidity and 65 to 75 degrees Fahrenheit — the same conditions as a comfortable living room.
If your home is very dry (below 40 percent humidity), use a room humidifier to add moisture to the air. If it is very damp (above 60 percent humidity), use a dehumidifier or place a small container of uncooked rice or silica gel packets inside the case to absorb excess moisture. Check the rice or silica every few weeks and replace it if it becomes wet.
A basic digital thermometer and hygrometer (humidity meter) costs under twenty dollars and lets you track conditions without guessing. Place one in the storage room and check it every two weeks.
Inspect the guitar every two weeks
Even in ideal storage, wood moves slightly over time. Every two weeks, open the case and look for visible cracks in the body, neck, or headstock. Check the fretboard for any warping or separation from the neck. Look at the bridge to see if it is still glued down flat or if it has started to lift at the edges.
Run your hand along the neck from the headstock to the body. It should feel straight. If you notice a hump or a dip, the neck may be warping and you should move the guitar to a more stable environment or have it checked by a repair person.
Check the tuning pegs and bridge for rust or corrosion, especially if you live near the ocean or in a very humid climate. Wipe away any rust with a dry cloth and explore a thin coat of light machine oil if needed.
Adjust storage if you notice changes in the guitar's condition
If the fretboard looks dry and cracked, the room is too dry. Add a humidifier or move the guitar to a more humid room. If you see mold or mildew on the case or the guitar, the room is too damp. Remove the guitar when ready, wipe it down, and move it to a drier space with better air circulation.
If the neck has developed a hump or a dip, or if you see cracks in the body, the storage conditions have changed or were not stable enough. Move the guitar to a climate-controlled closet or storage unit and consider having it inspected by a guitar repair person. Some damage can be reversed if caught early, but waiting makes it worse.
If you are storing multiple guitars, do not stack them on top of each other, even in cases. Store them upright in a guitar stand or lay them flat side by side with padding between them. Stacking puts pressure on the lower guitars and can warp the necks.
Long-term storage beyond six months
If you are storing a guitar for longer than six months, check it once a month instead of every two weeks. Loosen the strings a little more if they are still under tension — you want them slack but not completely loose. Keep the humidity and temperature stable and consistent.
Before you take the guitar out of storage to play it again, let it sit in the room where you will play it for at least a few hours so the wood can adjust to the new temperature and humidity. Then tune it slowly, a quarter turn at a time on each peg, and let it sit for another hour before playing. The wood needs time to settle after being stored.
Frequently Asked Questions
Can I store a guitar in a closet with my clothes?
Yes, if the closet is inside a climate-controlled room and not exposed to direct sunlight or heating vents. Closets tend to be more stable than other rooms because they are insulated from temperature swings. Make sure the closet is not damp and that nothing heavy can fall on the case.
Should I store the guitar with the strings tuned to pitch or completely loose?
Loosen the strings but do not remove them entirely. Slack strings reduce tension on the neck, but strings that are completely loose can slip off the tuning pegs or bridge. Aim for about half tension — the strings should be visibly slack but still attached at both ends.
What humidity level is too dry for a guitar?
Below 40 percent humidity is too dry and will cause the wood to shrink and crack. If your home stays below 40 percent in winter or in a dry climate, use a room humidifier or store the guitar in a case with silica gel packets to maintain moisture.
Can I store a guitar in a hard case standing upright?
Hard cases are designed to be laid flat, not stood upright. Standing a case upright puts all the weight on the bottom corner and can warp the case or put pressure on the guitar inside. Always lay the case flat on a shelf or the floor.
How often should I play a stored guitar to keep it in good condition?
You do not have to play it to keep it in good condition if the storage conditions are stable. However, playing it once a month helps you catch any changes in the neck or tuning early. If you do not play it, just inspect it visually every two weeks.
