Here's how to make the most of your Time Traveling Warriors long sleeve t - shirt. Wear it for casual outings or to show your love for the concept of time - traveling warriors. When it comes to washing, turn it inside out and use cold water. Wash it with similar colors to keep the colors bright. Only use non - chlorine bleach if there are stubborn stains. After washing, hanging it to dry is the best way to maintain its shape and quality. If you're in a hurry, you can tumble dry on cool or low heat. Remember, fabric softener can fade the colors, so skip it. Also, avoid ironing and dry cleaning as they might damage the fabric.
