In general, hand wash these panties in cold water with a mild detergent, avoiding bleach or harsh chemicals. Gently agitate and rinse thoroughly. After washing, gently squeeze out excess water without wringing or twisting the fabric. Air dry the panties in a well-ventilated area, avoiding direct sunlight or high heat sources. Store them in a cool, dry place, separate from other garments, and fold them neatly to maintain their shape. Ironing is typically not necessary.
