WFMW Putty Knife?

So let's say you're mopping and you come across a stubborn spot. You know, the kind where you let it soak for a minute, then come back to it, and it still won't come out. What do you use then, your fingernail? Gross. I use a plastic putty knife, about 1"-2" wide to scrape the spot right off. When I'm done with an area, I wrap a paper towel around it and use it to clean that crevice next to the baseboards. Ugh. You can pick one up at the hardware store for a buck or two, but if you're a do-it-yourselfer, you probably have one lying around that you can recycle. Make sure it's plastic, so it won't scratch anything. I wouldn't try it on a waxed surface, but it's good for tile, linoleum, and laminate flooring.
