Clean before storing.Stains from seemingly clear substances like body oils, perspiration, white wine and sugary substances may not appear for some time. Once these have a chance to oxidize, they may show up as light brown or yellow splotches that are difficult to remove. Before putting away seasonal items for long-term storage, have them dry cleaned. Dry cleaning to remove visible and invisible stains before insects find them is important to prevent unexpected surprises a few months down the road.Hang safelyUse wide, padded hangers for delicate fabrics so the material of the shoulders doesn't stretch or wear out. Don't cut hanger straps out of tops and dresses—use them to reduce stress on the rest of the garment. Hang suit jackets on wide wooden hangers to help them keep their shape. And give things room to breathe in your closet—they can touch, but don't cram them in.Don't use plastic.Do not store clothing in plastic garment bags. The plastic breaks down over time and can interact with the fabric, which can weaken it or change the color. Plastic can also trap in humidity that can lead to mildew damage. Garments need to be able to breathe, so wrap them in plain cotton sheets or a cloth garment bag to keep them safe.
