Here's how to use and take care of your Raffiti Jurassic Dad sweatshirt. First, when it's time to wear it, just put it on like any other crewneck sweatshirt. It's suitable for various casual occasions. When it gets dirty, machine wash it in cold water, and turn it inside out to protect the print. Wash it with similar colors to avoid color bleeding. Only use non - chlorine bleach if there are stubborn stains. After washing, you can either hang it up to dry for the best results, or use your dryer on a cool or low - heat setting. Don't use fabric softener because it might make the colors fade. And remember, never iron or dry - clean this sweatshirt to keep it in good condition for a long time.
