How to use this Momma Gorilla long - sleeve t - shirt? Simply put it on and enjoy its comfort and unique design! When it comes to maintenance, always remember to machine - wash it cold and turn it inside out to protect the color and fabric. Wash it with similar colors to avoid any color bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, hanging it to dry is the best option, but if you're in a hurry, you can tumble dry it on cool or low heat. Never use fabric softener as it can make the shirt fade. And stay away from ironing and dry - cleaning to keep the shirt in great shape for a long time.
