The curtains over my kitchen sink have gotten stained by the steam from hot water. Any way to get it out? - chicago curtains

It is probably polyester blended with cotton. Beige and brown spots are like veins. I live in Chicago, I think our water is hard enough. Steam can do that? Washing with the tide and Oxyclean me. Any help would be very grateful. They have little sewn around the edge of grapes and they are very nice. No, I want to replace them!
