Any Way to Get Rid of Stain That Has Set?

I'll buy my toddlers cloths from yard sales and soak them over night with a mixture made up of 1 cup powder dishwasher soap and 1 cup Clorox 2 put in a large bucket diluted with water up to the top. Soak over night and pour cloths and the whole bucket of solution in the washer and wash as you would normally do. remember to add you regular laundry soap with it. This soak has been able to get out stained cloths that I have bought so I don't see why it wouldn't work on your pants.

Try rubbing some Dawn dishwashing detergent into the stain and wash it again. It works (almost!) every time for me.

I use Dawn dish soap as well when I have a weird stain and it helps most of the time. I just squirt in on there, rub it in and let it "marinate" over night at least, then wash normally. I like Bttrfly's suggestion too, I may have to try that.

What type of material is it? What color is it? Goo gone is supposed to be really good and I have had good success with it the only thing is it has like an "oil-base" to it although I have used it on clothes before and never had an issue with it. Once I had a shirt that had an oil-base stain to it and it took it right out.

Thanks S.S. for asking! I have been wondering this myself. I washed/dried my daughters sundress and pulled it out to see a huge stain! She had only worn it once, but its ben hanging in her closet til I figure out how to get it out. Thanks for the advice, Bttrfly!

Oxy powder, soak it overnight. Begin with hot water to dissolve it and then soal the pants. Wash like normal, air dry to see of the stain is still there. Repeat if needed.
