To use this Arinesart sweatshirt, simply put it on and enjoy its comfort. When it comes to washing, make sure to turn it inside out and wash it in cold water with similar colors. Only use non - chlorine bleach if there are stains. After washing, you can either hang it to dry for the best results or use the tumble dry setting on cool or low heat. Be careful not to use fabric softener as it can make the colors fade. Also, avoid ironing and dry cleaning the sweatshirt to keep it in good condition.
