I used this product as directed and 12 hours after removing the 2nd envelope the stain was gone. It's a little difficult to get a peanut butter-like mixture, but stirring slowly got me there. The product visibly lightened the stain after the first application, but the second did. In both cases, one has to wait 12 hours after removing the envelope to see the effect. When I waited after the 2nd treatment the stain was gone. It took patience.
