I have a laundry stain removal question (please see details inside).

So, I’ve got this light-colored pair of pants that have some blue stains on them. They might be ink, or they might have come from another article of clothing that was wet and was left on top of the pants for too long.

Anyway, I’ve tried Henney’s laundry stain remover and Motsenbocker’s Lift Off but they didn’t work. Next, I tried DidiSeven, and this did lighten the stain about 50%. The instructions say that if the stain isn’t removed completely, to keep repeating the treatment.

But I want to look for something better. Have any of you used any of the following products: Tide Oxi Stain Remover, Oxi Clean Stain Remover, Shout, Goo Gone, Carbona. How well do these work, and were you happy with the results?

Also, what do you think of using hydrogen peroxide on ink or dye stains? Would this substance harm the fabric (cotton, in this case)?
