The only reason we use hot water to wash dishes is because I just cant bring myself to stick my hands in cold water. But, we don't go out of our way to heat it up either, I know it will never get hot enough to sanitize and even if it did I wouldn't want to stick my hand into that either! We get it just hot enough to be comfortable, so maybe a nice warm water would be a better description there.
We don't use anti bacterial anything. The dish soap we do use has grease cutters in it, and DW has been known to add vinegar as well. I thought at first, "man, rinse those dishes cause I don't want any vinegar taste or smell left over!'. But that never happened so I don't bother her.
She even makes a lot of our household cleaners herself, saves money! People tell us we are not being safe because we don't buy fancy anti-bacterial washes and soaps and hand sanitizers all the time. But then when you ask them, they use tons of the stuff and yet their kids have all these allergies and illnesses the parents don't while my kids are healthy on every Dr. checkup. Our Dr. even remarked that the only time she has seen my 10 year old daughter in the last 8 years that she has been their Dr. is for her regular checkups and school physicals (well that and a couple of minor injuries).
I really think there is something in this theory that using all these things is putting us in danger and would love to see a long term study on the subject. Then again I would love it if they took the 'foaming' agents out of the soaps as well, they serve no purpose other than to give us visual 'proof' that the soap is there and working.
Ever seen a river where this stuff runs off into? Filled with the foam... yick. I also worry about the effect of all these chemicals on the environment. I remember growing up we had to start treating our well water because it had become undrinkable due to the enormous amount of chemicals the farmers where pumping into the soil and onto the crops. And yet, no laws passed to reduce this despite the fact that all ground water out there now has to be treated to be drinkable. Smokers even had a standing joke that water would get them long before the smoking did.
They were probably wrong, but still...
