I have to agree with the nurse about the anti-microbial products and here's why--
We all (humans and animals) have a "natural flora" of bacteria that live on and around us. Every surface around us has bacteria, unless it has just been highly disinfected. Sounds wierd, maybe gross, but that's just the way it is. If you have the natural flora that is what you "should have" it will keep you healthy by crowding out nasty bacteria that can make you really sick. That is one reason you get fungal and digestive problems from being on antibiotics. The "good guys" are not there to protect you. When we kill off the "good guys" with anti-microbial products, washes, etc...the bad germs have an open slate to multiply, and the ones that survive could be really nasty for us or for our animals. I think it is much better to maintain a common-sense level of cleanliness, and not try to achieve some pure, super-clean state that does nothing for our animals, and may potentially harm them. Dirt has been given a bad name (along with bacteria!).
