Saliva from the human who’s blood it is works great too.

Here’s what I do and it works great. Use a surfactant, baking soda and a toothbrush. I use Folex cleaner, spray the stain and work baking into the cloth as a paste, scrubbing with the toothbrush a bit. Let it sit overnight at least but a day is about how long I leave it. Wash it with warm water in your machine. Almost always gets out grease on the first go. May take two times. Also works if your garment has previously been washed. Stain remover sprays work better than dish soap but a general surfactant is needed.

Why? Nobody can tell a difference over ~70 fps anyway.
