It's ironic that one of the best ways to clean up a mess in the kitchen is with something that can create a mess in the kitchen itself. We're talking about flour.
If the grease spill is a recent "oops" and the mess is still liquid, it's easier to clean it up immediately rather than wait until it becomes a sticky problem. To make sure you get all the grease up, sprinkle flour over the spill. The flour will absorb the grease and you can easily wipe it up. Just make sure it's cool before you touch it! This works great for a mess that hasn't dried yet. But if the grease has already started to get sticky and hard, try the next method on our list.
