How to remove washing creases from nurses uniform scrubs

Have you tried ironing it with a spray starch, such as Fabulon or Crisp? That should do it. And you don’t need to drown it either – a fairly liberal amount with a hot iron should do it

It’s probably due to the ‘starch’ in the uniform. This will go in time with more and more washes. Try giving it the hottest wash and spin drying it but iron it dry rather than hang dry. You can also try fabric softener.
