Jacket Lining Stained Nylon Shell?

I have this beautiful Nautica nylon spring jacket my 5 year old used to wear. I washed it in detergent powder in a bucket of water (fortunately) and the next thing I see it has blue stains from the blue interior lining. I want to be able to remove it and would like to hear from folks who had similar experiences. This jacket happens to be very expensive and I don't want to just toss it. I did read about RIT Color Remover but wonder if it will do it.
