dye stains on lugana

My 2 stitching pieces were up against a dark blue Yazi bag which got wet via my pet doing #1 on it, I soaked my pieces in dish detergent for 12 hours. I tried peroxide, lemon juice, orvis, oxiclean, baking soda and even javex for colours, nothing touched the dye stain...can anyone help?
