Cashmere items are a great investment, and it pays to care for them properly. To help keep your cashmere pants in excellent condition for years to come, we would advise always hand washing cashmere or having it professionally dry cleaned. Always turn inside out and use a delicate detergent. Enhancing the life of soft, luxurious cashmere is easier than you might think. Dry cleaning should only be done seasonally, to avoid damaging the fibers. Always turn inside out, and once washed, avoid wringing or twisting cashmere garments. Instead, press between clean, dry towels to remove excess water. Gently reshape, and then lay flat to air dry. When storing cashmere, always fold garments to avoid ruining the shape of the knit. ‘Pilling’ often occurs on even the best quality pieces, and a special cashmere comb can be used to brush them away.
