Here's how to get the most out of your Super Cool long sleeve crewneck t-shirt. First, when it comes to washing, just toss it in the machine on a cold cycle. Make sure to turn it inside out and wash it with similar colors. If it gets really dirty, you can use non - chlorine bleach, but only when needed. After washing, hanging it to dry is the best way to keep its shape, but if you're in a hurry, you can tumble dry it on cool or low heat. Remember, fabric softener can make the colors fade, so skip it. Also, don't try to iron it or take it to the dry cleaner. With these simple steps, your t - shirt will stay looking great for a long time.
