My Mom used this and swore by it throughout my childhood, I recently found a bottle of it in the tiny bottles like All 3x concentrated which I love because I have an HE washer and can only use so much soap in the dispencer. I don't think they should call it dual action as any detergent can be used as a stain fighter as long as it is not the cheapo stuff. I do really like it though and it smells good too.
