To remove food grease stains from clothes, all you need is a bottle of Murphys Oil. This really works!!
Pour a little Murphys Oil Soap on the item, let it soak before doing laundry
(don't let dry), then wash as usual. My mother-in-law was always telling me this. When my taco that I was eating dripped onto my favorite pair of jeans I immediately threw them into the washer, I even dryed them.
When I removed them from the dryer the stain was still there. My mother-in-law told me again to use Murphys Oil Soap on them. I didnt think that it would do any good since I already set the stain by drying them. But I went ahead and tried it. To my amazement it came out.
Now I always keep a bottle of it in my laundry cabinet. She made me a believer of it.
