Cotton Care
For men’s cotton shirts and garments, wash in cold or warm water using a mild detergent, avoid bleach, tumble dry on low or line dry to prevent shrinkage, and iron while slightly damp for best results.
Wool Fabric Care
To care for men’s wool jumpers, suits, and knitwear, hand wash in cold water or use a wool cycle with a wool-safe detergent, always lay flat to dry, steam out wrinkles instead of ironing, and store garments folded to avoid stretching.
Man-Made Fabric Care (Polyester, Nylon, etc.)
Men’s clothing made from man-made fabrics like polyester or nylon should be machine washed cold, dried on low or air-dried to avoid heat damage, ironed on a low setting or steamed if needed, and benefits from being wrinkle-resistant and low-maintenance.
