Store your guitar in a hard case or on a wall mount in a climate-controlled room

A guitar left in a basement, attic, or garage will warp, crack, or rust within months. The wood expands and contracts with humidity swings, the finish peels, and metal parts corrode. Your best option is a hard case in a bedroom or closet where the temperature stays between 65 and 75 degrees Fahrenheit and humidity stays between 40 and 50 percent.

If you play regularly, a wall mount or stand in your living space works just as well — it keeps the guitar visible and ready, and the stable indoor temperature protects it. Avoid leaning it against a wall or laying it flat on a bed; the neck can warp under its own weight or shift if someone bumps it.

If a hard case is not in your budget, a gig bag (padded soft case) is the next best choice for storage, though it offers less protection than a hard case if the guitar gets knocked over. A gig bag costs $30 to $80 and will keep dust and minor impacts away.

Key Takeaways

  • Hard cases protect against temperature swings, humidity changes, and physical damage — the three things that ruin guitars in storage.
  • Keep your guitar indoors in a room where the temperature and humidity stay steady, not in a basement, attic, garage, or shed.
  • Loosen the strings slightly if you are storing the guitar for more than a month, because constant tension can warp the neck over time.
  • Check on the guitar every few weeks and wipe the body and neck with a soft, dry cloth to catch dust and prevent buildup.

Why humidity and temperature matter more than you think

Wood absorbs and releases moisture based on the air around it. When humidity jumps from 30 percent to 70 percent, the wood swells. When it drops back down, it shrinks. This cycle cracks the finish, splits the body, and twists the neck. Guitars stored in basements or garages — where humidity can swing 40 points in a single season — fail fastest.

Temperature swings cause the same problem. A guitar in an unheated garage goes from 40 degrees in winter to 85 degrees in summer. The wood and glue joints expand and contract unevenly, and the frets can lift away from the fretboard. The finish also becomes brittle in cold and soft in heat, making it peel or crack.

A bedroom closet or interior wall of your home stays within a narrow range year-round. If you live somewhere with extreme seasonal swings, a small humidifier or dehumidifier in the storage space costs $30 to $100 and pays for itself by keeping one guitar safe.

Choosing between a hard case, gig bag, and wall mount

Hard cases are the gold standard. They cost $100 to $300 depending on the guitar size and case brand, but they protect against drops, temperature swings, and humidity changes. The case itself acts as a buffer, and most have latches that seal out dust. If you own a guitar worth more than $500 or plan to store it for months at a time, a hard case is worth the money.

Gig bags are padded soft cases that cost $30 to $100. They protect against dust and minor bumps but do not insulate against temperature or humidity the way a hard case does. They are best for guitars you play weekly and store in a climate-controlled room. If the guitar sits untouched for months, the padding alone will not prevent warping.

Wall mounts are brackets that hold the guitar by the headstock or body. They cost $15 to $50 and keep the guitar visible and accessible. A wall mount works well if the guitar is in a bedroom or living room where temperature and humidity stay steady. Do not use a wall mount in a garage, basement, or any room that gets cold or damp.

How to prepare a guitar for long-term storage

If you are storing the guitar for more than a month, loosen the tuning pegs so the strings sit at about half tension. The constant pull of full tension can warp the neck over weeks or months, especially in a young guitar or one made of softer wood. Loosening the strings also reduces the risk of the bridge lifting or the body cracking under sustained pressure.

Wipe the body, neck, and headstock with a soft, dry cloth to remove dust, sweat, and oils. Do not use furniture polish or water — these can seep into the wood and cause swelling or discoloration. A microfiber cloth works best.

If the fretboard is rosewood or ebony, you can explore a small amount of lemon oil to keep it from drying out, but this is optional and only needed if you are storing the guitar for six months or longer. Wipe away any excess oil with a clean cloth.

Store the guitar in the case with the tuning pegs facing up so the neck stays straight. If you are using a wall mount, make sure it is screwed into a stud or uses heavy-duty anchors — a falling guitar can be damaged beyond repair.

Monitoring your guitar while it is in storage

Check on the guitar every two to four weeks. Open the case, look at the body and neck for any new cracks or warping, and feel the strings to make sure they have not tightened on their own (which can happen if the room temperature dropped). If you notice the strings have tightened, loosen them again.

If you are storing the guitar in a case with a hygrometer (a humidity meter), check the reading each time you open it. If humidity is above 55 percent, place a small packet of silica gel in the case to absorb moisture. If humidity is below 40 percent, place a small humidifier packet in the case to add moisture. These packets cost $5 to $15 and can prevent serious damage.

Wipe the body and neck with a dry cloth each time you check on it. Dust buildup can trap moisture and scratch the finish over time.

What to avoid when storing a guitar

Do not store a guitar in a basement, attic, garage, or shed, no matter how dry it seems. These spaces experience wild temperature and humidity swings that will damage the wood and finish within months. Even an unheated bedroom closet is better than a climate-controlled basement if the basement is not actively heated and cooled year-round.

Do not lean the guitar against a wall or lay it flat on a bed. The neck can warp under its own weight, and the body can shift and crack if someone bumps it. Always use a stand, mount, or case.

Do not wrap the guitar in plastic or store it in a sealed plastic bag. Plastic traps moisture and can cause mold or discoloration. Use a breathable case or gig bag instead.

Do not store the guitar near a window, radiator, air conditioner, or heating vent. These create hot and cold spots that cause the wood to expand and contract unevenly. Keep the guitar away from direct sunlight as well — UV light fades the finish and can make the wood brittle.

Storage solutions for different living situations

If you live in an apartment with no basement or garage, a bedroom closet or the interior of a coat closet is ideal. These spaces stay at room temperature year-round and are protected from direct sunlight. A hard case or gig bag fits easily on a shelf or the floor.

If you live in a house with a basement, use it only if the basement is finished, heated, and cooled as part of the main climate system. An unfinished basement with a concrete floor will be damp and cold in winter and humid in summer — both will damage the guitar. If your basement is unfinished, store the guitar upstairs instead.

If you live in a very dry climate (like the Southwest), you may need to add moisture to the storage space. A small humidifier running a few hours a day, or humidity packets in the case, will prevent the wood from drying out and cracking. If you live in a very humid climate (like the Southeast), a small dehumidifier or silica gel packets will prevent mold and swelling.

Frequently Asked Questions

Can I store a guitar in a closet with other items?

Yes, as long as nothing heavy is stacked on top of the case and the closet stays at room temperature. Keep the guitar away from cleaning supplies, paint, or anything with a strong smell — these can seep into the wood and finish. A closet shelf works well if the case is not in direct contact with the wall.

How long can a guitar stay in storage without being played?

A guitar can stay in a hard case in a climate-controlled room for years without damage, as long as you check on it every few weeks and loosen the strings if you are storing it for more than a month. If you store it for longer than six months, play it for a few minutes every month or two to keep the wood and hardware from becoming brittle.

What should I do if my guitar gets wet?

Wipe it dry when ready with a soft cloth and leave it in a warm, dry room with good air circulation. Do not use a hair dryer or place it near a heater — rapid drying can crack the wood. Let it air-dry for at least 24 hours before putting it back in the case. If water got inside the body, tilt the guitar to let it drain and leave it open to dry for several days.

Do I need to tune the guitar before storing it?

No. In fact, you should loosen the strings slightly before long-term storage to reduce tension on the neck. When you take the guitar out of storage, tune it back to pitch and let it sit for a day or two while the wood adjusts to the change in tension.

Can I store a guitar in a car?

Only if you are driving it to a gig and will take it inside within a few hours. Cars heat up and cool down rapidly, and the humidity inside a car can swing wildly. Never leave a guitar in a parked car overnight or for more than a few hours, especially in summer or winter.
