How do you get the shipping wrinkles out of a polypropylene rug?

To remove shipping wrinkles from a polypropylene rug, first, lay the rug flat in a warm, dry area. Use a hairdryer on a low heat setting to gently warm the wrinkled areas, being careful not to overheat the fibers. Alternatively, you can place a damp cloth over the wrinkles and use an iron on a low setting to steam the area lightly. Finally, allow the rug to cool flat to help set the fibers in their new position.
