The stain was sprayed twice, rinsed with water 10 seconds later and then measured for residue. Oomph!™ cleaner was by far the most effective, removing more than 92 percent of the grease, far more than Purple Power or Simple Green. The simulation was conducted by STP scientists using a greasy particulate soil based on Sanders & Lambert (an industry standard soil).
