At ShirtSpace, we recommend following these special care instructions to keep your blank shorts in excellent condition: Machine wash cold with similar colors, using a gentle cycle. Avoid using bleach or harsh detergents. Tumble dry on low heat or hang to dry to prevent shrinking and maintain fabric quality. If needed, iron on low heat inside-out. By following these care guidelines, you'll ensure your shorts' longevity and vibrant appearance for seasons to come. If your shorts are made of synthetics like polyester, spandex or rayon, be very careful with high temperatures from hand-held irons since these materials burn or melt easier than cotton.
