I wanted this to work!

I purchased this from Amazon -quick shipping- based on reviews it was the best ever even for stubborn stains. I had tried everything having some success with Oxi-Clean (readily available everywhere including Costco) to remove spaghetti sauce from my husband's new dress shirt. I tried Grandma's Secret Spot Remedy 3 different times letting it sit between 10 -50 minutes before washing. It lightened each time even after scrubbing with a toothbrush as per a reviewer's tip. The stain although not quite as bright is still noticeable.
It was an expensive try that didn't work for me on what I would consider a typical stain.
