How Heat and Humidity Damage Your Favorite Things in Storage


We’re used to thinking of inanimate objects as insensitive to the things that bother humans, like very hot weather and high humidity, but the truth is that some of our belongings are extremely sensitive!


Certain items can be greatly damaged or completely destroyed by the effects of heat and humidity, but climate controlled storage can help prevent these sad stories. Here are some ways that many of your favorite things can become damaged during storage when exposed to heat or humidity.


Art Has a Breakdown

High humidity can cause mold to grow on paper or canvas. Plus, high temperatures may cause deterioration of art materials. Even sculptures are susceptible to the damaging effects of humidity and temperature. Damage to sculptures may come in the form of cracks, erosion, warping or color changes.


Vinyl Records Dream of Better Days

Heat and humidity can damage vinyl records beyond repair. Not only will the records themselves warp when exposed to heat, the paper album covers can develop mold with exposure to dampness from high humidity and temperature fluctuations.

Music and Movies Won’t Age Well

DVDs, CDs, cassette tapes and other forms of media can suffer a decline in image or sound quality with exposure to temperature extremes.


Electronics Long for Consistency

Cold, fluctuating temperatures and dampness are enemies of electronic devices, such as stereos, cameras, monitors, TVs and audio equipment. When cold equipment warms up again, condensation can form inside, causing damage. LCD screens and batteries are particularly susceptible to damage caused by temperature extremes.


Clothing Becomes at a Bit too Vintage

Clothing items exposed to high humidity are more likely to be ruined by mildew. And mildew doesn’t distinguish between designer suits or an old pair of sweatpants!


Upholstered Furniture Grows Unfit for Company

Furniture covered with fabric has a lot of area for potential mold growth. When mold forms on upholstered furniture exposed to high humidity, repair can be very difficult or impossible. And who wants a smelly sofa?


Wooden Furniture Cracks Up in a Bad Way  

Even the strongest wooden furniture can crack, split, warp or weaken when subjected to freezing and thawing temperatures. Wood reacts to temperature changes with expansion and contracting, which can cause considerable damage to antiques and family heirlooms.


Metal Furniture Gets Weak at the Knees 

Belongings made from metal may appear hardy, but when exposed to temperature extremes and humidity, they can corrode and weaken. Climate controlled storage is the best choice for preventing rust and other damage to metal items.

Comic Books Cry

During storage, comic books require a cool and stable environment with low humidity. Environmental fluctuations can cause moisture to develop, and water and paper don’t belong together!


Newspapers Headline Mold

Newspapers are difficult to preserve, and they’re especially vulnerable to damage caused by heat and humidity. Moist, warm air causes mold spores to sprout on paper, and humidity causes newspapers to split and curl. In addition, high temperatures speed up the reaction of acids in the paper.


Photos Break Up

Storage spaces without climate control can experience high heat and humidity followed by cooling temperatures. Those conditions cause photographic images to crack or separate from the photo paper.


Wine Gets a Cloudy Headache

Long-term exposure to high temperatures can affect wine’s quality and its ability to age. In addition, high heat can alter the look and stability of wine, making it appear unappetizingly brown or cloudy!


Toys Become Sad and Moldy

Humidity is no good for some toys. Cardboard boxes containing unopened vintage toys can become moldy when exposed to humidity. And stuffed animals are notorious for developing mold when exposed to humidity.


Relax with Climate Control

While all of the conditions described above sound upsetting, they’re easily avoided. With climate controlled storage, your favorite things are protected with a constant environment between 55 and 85 degrees Fahrenheit!
