My favorite trick for grease is using Goop - that gelatinous stuff they sell in the automotive section for getting grease off hands. Dab it on while the garment is dry and the launder as normal. I had shirts that I had given up on that had been washed and dried multiple times and then I read about Goop somewhere and they came out. It is now my go-to for all greasy spots on clothing. Hope that helps.
