RE: Host of questions for the crunchier mamas...
Eri-for the raw milk, maybe try posting over at MDC? DH and I drink raw milk but we don't give it to DS. I'd consider it if it was tested for tuberculosis and brucella (?) but I'm not 100% sure ours is. It is a very small family owned farm with a small herd of cattle so the risks are quite low in our case. In PA since raw milk is legal, I think it has to be tested. In any case, I am not sure if I want to give it to DS or not...
If you heat it it should kill the bacteria as you said. I would think just to boiling or just under? FWIW, it does kill the beneficial enzymes in the raw milk once you go over 118 F I believe so that's something to consider. Anyway, we drink it but I don't have experience w/ giving it to DS as he doesn't drink cow's milk. He does eat organic raw milk cheddar though and loves it...but his constipation issues don't ;)
In the vaporizer you could try a few drops of eucalyptus essential oil I would think? I used to add a few drops to the bath water (like 3 drops) when DS was sick or stuffy, and when he had the croup. The steam alone would probably work fine. I don't want to break your vaporizer though so you might want to double check with someone else about whether or not E.O. is okay to put in there ;)
For floors I just use vinegar and water (white vinegar because it is cheaper) and my schmop which is a microfiber mop. Sometimes I add a few drops of essential oils...tea tree, lavendar, whatever I'm in the mood for :) For scrubbing most things I use a paste of baking soda water or baking soda and vinegar.
