How to remove Dawn dish detergent stains?

Question

I advised my husband to attempt to remove grease stains from his shirt by using Dawn dish detergent. He applied the detergent directly to his dry shirt and then wet it but did not rub it in. After washing there are color spots from the detergent remaining. Any ideas on how to remove these?

Answer 1

spray and wash  or just soak the shirt in cold water for a couple of hours to see if that works

Answer 2

try WD 40  I no it sounds crazy.  But sometimes it works.
