We recommend machine-washing your pullover and slipping your piece into a cover.
Use a cold setting with a dose of laundry detergent.
Start your program and slow dry.
You can also hand-wash it in cold water: quickly dip your piece, pat it, and rinse it in clean water.
Wring your sweater in a terry towel without pulling it out of shape.

Then, dry it flat, away from light and heat.
