Here's how to get the most out of your DinoMike 'Go Green' long sleeve T-shirt. First, when it comes to washing, use cold water and turn the shirt inside out. This helps keep the colors vibrant and the fabric in good shape. Wash it with similar colors to avoid any color bleeding. Only use non - chlorine bleach if it's really dirty. After washing, hanging it to dry is the best way, but if you're in a hurry, you can use the cool or low - heat setting on your dryer. Remember, fabric softener can make the colors fade, so skip it. Also, don't iron the shirt or take it to the dry cleaner, as these can damage the fabric. This way, your T - shirt will stay looking great for a long time.
