Wet cleaning is the best method for acrylics. They dry rapidly and are resistant to bleaches, diluted acids, and alkalis. Acrylics are highly resilient to shrinking, mildew, and sunlight. Most are also very wrinkle resistant and can be dyed using various methods.
Use caution with heat, as acrylic fibers are heat sensitive, prone to pilling, and can retain oily stains. Acrylics are the synthetic version of wool. Wool, however, is much more sensitive. Unlike wool, you can use alkalis with warm water and leave them with a longer dwell time on acyrlics. Agitation works best in a circular motion. Some common trade names for acrylic are: Acrilan, Creslan, Dralon, Orlon, and Zefran.
Warning: Always test materials for colorfastness, follow label directions, and never mix products unless specified in the label directions. Each situation reacts differently and results may vary.
