Here's how to use and take care of your Ben Swolo's Gym long sleeve crewneck t - shirt. Just put it on and show it off! When it's time to clean, turn it inside out and wash it in cold water with clothes of similar colors. Only use non - chlorine bleach if it gets really dirty. After washing, hanging it to dry will keep it in great shape, but you can also use the cool or low - heat tumble dry setting. Remember, don't use fabric softener as it can make the colors fade. And never iron or dry clean the shirt to keep its quality intact.
