Oh Poop!

Calling all Mommas! I need your tips on how to get a poop stain off of Elise's portable changing pad. She had the mother of all blowouts (I didn't realize it until I opened her sleeper and saw it all up her back, and by that time it was too late), and it got onto the white changing pad I use to change her when I'm downstairs. I washed it off almost immediately, but there's still a "brownish hue" that remains.

Any ideas? Anyone?


Edited to add: Thanks for the suggestions. I didn't have any Oxiclean, but I found some cleaning stuff that had "Oxypower" (whatever that means). It worked! Looks like I should add Oxiclean to my shopping list though...
