First make a solution of about a teaspoon of the regular blue Dawn dishsoap and 2 cups of warm/hot water. Next, wet a white cotton cloth with the dishsoap solution and then wring it out so that it isnt sopping wet. Lay it over the stain ( I also got the stain wet with the solution too before I laid the cloth on it). Now heat your clothes iron up on the lowest setting and then set it on top of the cloth and leave it there for about 15 minutes. You may have to repeat this a couple of times depending on how old the stain is but it really works! Dont rub or press on the iron. Just let it sit there and somehow the heat pulls out the red dye. It is so cool. Apparently this is how professional carpet cleaners get stains out of carpet. Now you dont have to pay anyone to do it for you!
Here are a couple of pictures: the first one shows the red stain after all other attempts to get it out failed. This was as good as I could get it out without the new trick. The next picture shows the cloth after I laid the iron on it.....see all the red it pulled out! I am happy to say that the stain is gone!
