1. Sweaters. Washing: While wool sweaters are best hand-washed, sweaters made of other materials can be machine-washed.When washing wool sweaters, follow the "two don'ts and one must" principle: Do not agitate in the washing machine; avoid alkaline detergents—use neutral detergents to prevent fiber damage; adopt a pressing method by soaking the sweater in water and gently pressing it. For heavily soiled areas like collars and cuffs, lightly brush with a toothbrush.Drying: After washing, roll the sweater in a towel to press out excess water. Lay flat to air-dry; avoid sun-drying to prevent shrinkage. If dampness remains after air-drying, place the sweater in a paper bag and use a hairdryer on low heat for 2–3 minutes to remove residual moisture. Storage: Sweaters are fluffy and save space when rolled. Avoid hanging to prevent distortion.
2. Down Jackets. Washing: Dry cleaning removes the protective outer layer, so water washing is essential. Pre-treat stains first: soak heavily soiled areas like cuffs in hot water, sprinkle with detergent, let sit for 30 minutes, then gently brush.Drying: Proper air-drying and fluffing prevent clumping. Hang down jackets in a shaded area to air-dry, avoiding direct sunlight. After drying, use a small piece of cut-off hose with one end trimmed into a brush-like shape to fluff and evenly distribute the down.Some down jackets develop yellow stains when stored for a year, caused by mold from moisture. Ensure thorough drying to prevent musty odors. Storage: Roll for space-saving storage, but avoid vacuum-sealed bags. These can permanently flatten the down and cause wrinkles when removed the following year.Cleaning: Synthetic leather can be washed with soapy water and gently scrubbed. For genuine leather jackets without obvious stains, simply wipe with a cloth dampened in soda water and air-dry. Genuine leather is prone to mold. If mold spots or stubborn stains appear, dry cleaning is recommended—avoid vigorous scrubbing. Storage: Hang in a dust cover and periodically dehumidify.
