Dirty Laundry

Did I fool you by the title? Did you think I might tell you some deep, dark secret? Think again, friends! I simply need some advice on getting out set-in stains on clothing. I did a few loads of laundry on Monday. As I went to put things away today, I noticed four of Isaac's shirts now have stains on them. I didn't catch this before adding them to the wash, so now I'm not sure if I can tackle this dilemma. Arrrggh! Any ideas? I know many of you rave about OxiClean. Do you think it might work? If you have any suggestions, please leave a comment!
