I agree with the essential oil idea. I usually add a few drops of pine. Smells better than the commercial stuff!! Dh recently went all out and got me a big treat....a bottle of Frankinsense essential oil ($35.00 here in Canada!!) and I've mixed that with vinegar......quite decadent!!! LOL!
I use vinegar for everything....bath, kitchen, floors, windows. I have managed to get all commercial cleaners out of the house, but it was tough to give some up!!! I think if you maintain a tidy home (
: ) "germs" shouldn't be an issue for you to worry about. A microbiology professor of mine told me that "germs" are not defined, therefore, "germ killing" and "germicidal" have no definition. And if they have no definition, the companies can basically put anything in a bottle and sell it to you. SO, they plaster products with the word "germ", making us believe that we really wallow in disease and need the stuff.....but we're pretty clean creatures, and I suspect a good swipe with vinegar will be just fine!!!
I'm no expert, just my $0.02!!!!
