What are the practical differences between washing your hands and using hand sanatizer?

Please let me know if I should change the flair. Thanks!

Hand sanitizer does not kill everything that can harm you. for example C-difficile spores just get smeared around in hand sanitizer yet remain capable of causing infection. Hand washing actually removes and rinses bacteria and viruses away from the hands.
