Here's how to get the most out of your Sai Mastery sweatshirt. First, when it comes to washing, just toss it in the washing machine on a cold cycle. Make sure to turn it inside out and wash it with clothes of similar colors. Only use non - chlorine bleach if there are stubborn stains. After washing, hanging it to dry will keep it in great shape, but if you're in a hurry, you can use the tumble dryer on a cool or low - heat setting. Remember, fabric softener can make the colors fade, so skip it. And don't try to iron or dry - clean this sweatshirt as it may damage the material. This way, your sweatshirt will stay looking and feeling great for a long time.
