One of the negatives of eating greasy food other than gaining weight is when the grease falls on one's shirt it leaves an almost indelible spot. After one launders the garment the grease spot still remains as a shadow of itself. I have tried many laundry spotters or grease removers all of which have fallen short. The thing that works is a pan cleaning product. It is called Dawn Power Dissolver. It is found in the kitchen cleaner section of the grocery store. It is in a Blue plastic bottle with a finger pump sprayer. I have used it on both cottom and man made fibers and is color safe. It is often hard to find. So yes, this message is self serving in that I hope there will be more demand for the product. BUT IT DOES WORK!
