How to remove dried stains?

I've looked online for answers on how to remove them, but its only telling me stuff on how to remove stains that havent dried yet so im hoping someone can help me here on funadvice.

Alright,

So, I have a stain on my white shirt, a soda stain to be...

exact. and I cant seem to be able to get it off. I tried bleach but it doesnt work, if anything it makes it worse I think? Does anyone know how to remove dried on soda stains?

yea I dont knw what to tell yea! maybe live in hott water (and I mean hott!) for a couple hours and try scrubbing it out.

Try oxyclean. You have to apply the oxyclean paste (instructions are on the package) and let it sit on the stain for a while before you wash it.

Believe it or not, shampoo will get a lot of stains out. If it doesn't work this time, don't give up. It really works on most stains.

well.. what kind of shampoo?

Carbona Stain Devils products get all stains out, just as long as you have not dryed it in a dryer yet, the stained clothing can air dry on its own and all Carbona products will still work just as long as nothing has been dryed in a dryer...
