The answer to your question is that neither scenario leaves the object completely germ free. If you’ve ever seen the commercials for the antimicrobial soap, they say, “eliminates 99.9% of germs.” Sounds terrific, right? But, consider that there are millions to billions of bacteria on your hands or kitchen surface. If you kill 99.9% of 1 million bacteria, that still leaves 1000 bacteria (this is what is called a 3 log kill). In addition, there are bacteria that are fairly resistant to hydrogen peroxide or soap, so basically, you can’t really truly and completely sterilize objects with the tools you described.
