Here's how to use and take care of your Arinesart long sleeve crewneck t - shirt. Just put it on like any other t - shirt and enjoy its comfort throughout the day. When it's time to clean, turn it inside out and put it in the washing machine on a cold cycle with similar colors. If it gets dirty, you can use non - chlorine bleach, but only when really needed. After washing, it's best to hang it to dry. If you're in a hurry, you can tumble dry it on a cool or low - heat setting. Remember, don't use fabric softener because it might make the colors fade. Also, avoid ironing and dry - cleaning this shirt to keep it in great shape for a long time.
