Sleeve and Jacket
According to the Vinyl Record Storage website, the most crucial step to avoiding scratches is storing your record in a paper sleeve and cardboard jacket. All new vinyl albums come with their own sleeves and jackets, but many vendors sell used records without any form of packaging.
Conditions
Store vinyl albums in a cool, dry place. The ideal temperature for vinyl storage is 65 to 70 degrees Fahrenheit, according to Eil.com. Too much heat will cause the records to warp or bend, resulting in wavering sound quality. If the storage area is too humid or damp, the records will grow moldy and unusable. Too much sunlight causes the cardboard jackets to fade, so keeping the vinyl albums out of direct sunlight is also important.
Positioning
Never stack vinyl albums on top of each other horizontally, as the pressure will alter the grooves and ruin the sound. Store records vertically to avoid any stress or pressure. Many collectors store their vinyl albums in floor racks specifically designed for records, allowing them to rest straight up.
Dust
Vinyl albums will undoubtedly collect dust, and it is okay to gently brush them from the inside out with a light, dry rag. Never spray liquid dust remover on the records, as this will cause permanent damage.
