Uncrease refers to the action of removing creases or wrinkles from a garment or fabric. There are several synonyms for the word 'uncrease', including iron, smooth, flatten, press, and straighten. Ironing is the most common way people uncrease their clothes and remove wrinkles. Using a flat iron or a steam iron and applying heat straightens the fabric. Another way to uncrease clothes is by placing them under a heavy object to flatten them out. Additionally, using a garment steamer or wrinkle releaser spray is also helpful in smoothing the creases away. Choosing the right method of uncreasing garments is essential to maintaining the durability of the fabric.
