Works great on set in and new stains like grease and mud.
I use one scoop with every load and it has well exceeded my expectations!  First time used, my jeans that I had thought were ruined and turned in to work jeans, came cleaner than they had since they were new. They had grease, mud and a lot of grime, having worn them to change a wheel bearing on my vehicle. Strongly recommend this product and just a scoop with every load along with your regular detergent.
