Set the machine to the gentle cycle using a cold water setting. Avoid using chlorine bleach on modal fabrics. When you remove the clothing from the washer, give each piece a good shake to help release wrinkles. Modal should be dried at a temperature between low and medium-high, and the items should be taken from the dryer while slightly damp to reduce wrinkling. Knitted modal fabrics are resistant to wrinkling if removed from the dryer immediately and then folded or hung. Woven modal fabrics like cotton usually need a bit of ironing to look crisp. Steaming your modal garment will also work to loosen wrinkles.
