I think my 2 year old is grinding foodstuff into her shirts! She has a couple of off white/vanilla shirts that have stains on them (I am assuming they are food stains) that absolutely will not come out! I have tried Shout stain spray Triple Acting, Shout Advanced, Oxiclean AND the Clorox Bleach Pen and the stains are still there!?

I am a loss, when I tried all these (a couple of times for Shout Advanced), I would not dry before trying something different.
Anyone have a suggestion as to what I have not tried and might work? I am getting ready to throw them in with a white sock bleach load but at this rate, not sure if would do anything at all!?
