Cleaning Products that kill 99.9% of germs: are these not simply leaving the strongest 0.1% to survive and repopulate?

We see this in antibiotics (MRSA followed Methicillin by ~5 years, I read). Why does something similar not seem to happen in our households/environment? And if it *does* happen, are we not better off using soap and water, or just bleach?

Most of those cleaning products use alcohol or something similar, and germs can’t evolve a resistance to that in the same way that they can adapt to antibiotics. 

The germs that survive antibiotics have a mutation that makes them more resistant, but the 1% that survive those cleaning products don’t do so because of a mutation, they only survive because there will almost always be some small surface area that isn’t fully exposed to the cleaner. So we aren’t really leaving the strongest germs behind, just the luckiest, and that’s not an adaptation they can pass on.
