This Arinesart sweatshirt is super easy to use. Just put it on and enjoy its comfort! When it comes to washing, remember to turn it inside out and use cold water. Wash it with clothes of similar colors to avoid color bleeding. Only use non - chlorine bleach if really needed. After washing, you can hang it to dry for the best results. If you're in a hurry, you can tumble dry it on a cool or low - heat setting. But stay away from fabric softener because it can make the colors fade. And don't try to iron it or send it to the dry cleaner, as that might damage the sweatshirt.
