Best Way to Clean Axle Grease

So today I have to put the brakes back together, put the serpentine belt on, and top off the transmission fluid. But before I do that I have to clean up all the grease that has been slung everywhere. What's the best way to clean this gunk up?? It's EVERYWHERE!
It's been over a month since I've driven it. I'm actually excited about driving it!
