We like to think that we can do anything. After all, with a little Internet research and a few well-picked videos, couldn't anyone write a novel, fly an airplane, invent something new, or discover a new subspecies of beetle? Okay, maybe not. But the truth is, when we put our minds to it, we can get a lot accomplished, even if it's not flying an airplane or discovering a new beetle. One area where we're fairly confident about our expertise is in cleaning. After all, we've been cleaning one way or another for most of our lives.
