This is a pretty stupid question but I don't know the answer. What is the best way to clean up a coolant spill from a cement garage floor? I spilled some antifreeze when I installed a new water pump. I'm sure I'm not the only person dumb enough to try cleaning up antifreeze with floor-dry (cat litter). Actually, I've made that mistake twice now ... For those who haven't tried that, it creates an evil frictionless mud on your floor that never goes away. So really, I have two problems now - What should I have used when I had antifreeze on my floor? What will clean up the evil mud?
