ANSWER:
If you drop soap on the floor, not only is the floor still dirty, it's also slippery. Soap doesn't magically remove dirt. It simply loosens dirt from whatever surface it's stuck to, so that it can be washed away. Without water, soap is useless.Instead, put it in the washing machine. If the soap has visible dirt on it, spray it off with a heavy jet of water. After that, all that will be left on the soap is microbacteria and other such dirt. DO NOT touch it with your bare hands.
