I had an old stain on a carpet in my house and I tired a new way to get it out. I used laundry detergeant and water and rubbed that in really good. Then I put two sheets of paper towels over the area and used an iron to go over the paper towels. To my amazement the stain was soaking into the paper towel. I just repeated these steps a dozen times and it eventually came out. Then I tried it on a coffee stain on my seat in the truck and that came out right away. Give this method a shot you have an old stain that won't come out.
