Master Your Hand-Washing Technique
As with any item you’d like to keep looking great, read your sweater’s care instructions before cleaning. For hand-wash cashmere, try this technique from Real Simple: First, fill a clean sink with slightly warm water (about 85 degrees Fahrenheit) and add a small amount of gentle fine-washables detergent. Baby shampoo is a good choice. Place your sweater into the sink, and swirl it around in a circular motion. Never stretch, pull, or rub the fabric together. Twirl for two to five minutes.
Drain the suds and refill the sink with clean water, keeping the garment in the basin. Avoid allowing the water to beat directly onto the fabric, which could cause it to stretch. When no suds remain, drain the water. Create a loose ball with the wet fabric and press it against the side of the sink to release as much water as possible. Do not wring it out (this could do just as much damage as tossing it in the washing machine).
Place a large towel on a flat surface and lay the garment on top of the towel, smoothing out all of the wrinkles. Starting at the top of the sweater, roll the towel and the garment together, pressing down on the roll to help the towel absorb the water in the sweater. Unroll. Place the sweater on a mesh drying rack away from radiators and direct sunlight until it’s completely dry.
Never Toss Spare Buttons
Put each sweater’s spare buttons someplace you’ll be able to find them again. One idea we love is this business-card organizer that keeps all of your spare buttons, thread samples, cloth tags, and fabric-care labels in one place. Pick up the organizer from an office-supply store, and slip your spares into the compartments.
Store Sweaters Safely
Once spring comes around, make sure to pack your sweaters away carefully. First, make sure they are are clean. Even if an item doesn’t look dirty, remnants of food, sweat, and perfume can attract moths. Next, fold each one using white tissue paper (colored paper could stain your clothes).
