Un-creases are those stubborn folds on our clothes that refuse to go away easily. Fortunately, there are a handful of synonyms that can be used to describe the process of removing these creases. One of the most common alternatives is "smooth out," which implies straightening the fabric until it's wrinkle-free. "Iron," on the other hand, suggests using an actual iron to press out the wrinkles. Another synonym worth considering is "flatten," which means to remove any bumps or folds by applying pressure. The word "press" can also be used to describe the act of ironing or smoothing out wrinkles. Finally, "steam" is a synonym used when applying steam to a garment to loosen and remove creases.
