Pork fat is a genuine pain in the ass to clean up. I go through more dish soap, scouring pad/sponges and hot water that way, but I try not to let it stop me from enjoying the occasional pulled pork sandwich or homemade bacon bits.
Get some “Awesome” from the dollar store. It works great on grease.... If your fingers feel slippery it’s because it melting of a layer of skin. I think it’s lye based.
