Leather and suede items, such as jackets or handbags, should never be immersed in water. Washing machines can cause irreparable damage to these materials, leading to discoloration, cracking, and stiffness. Instead, wipe down leather and suede with a damp cloth or use specialized cleaning products designed specifically for these fabrics.

Rayon and viscose fabrics are made from natural fibers but require delicate handling to avoid shrinkage or distortion. These fabrics are best cleaned through hand washing or dry cleaning. If you must machine wash them, use a gentle cycle and place the item in a mesh laundry bag to reduce friction.
