I have used vinegar and baking soda for cleaning for at least 14 years (I started all this great stuff around the time my first son was born) but when my second son was very young he let me know, in no uncertain terms, that he could not abide the smell of vinegar. Even now, at age ten, every time I spray vinegar somewhere E calls out "Eeeew, vinegar!" from wherever he is in the house (He used to call it "Vinekar" and the bottle of vinegar we use as a hair rinse still is labeled that way thanks to his older brother). When I came across the idea for putting orange peels in vinegar and letting it sit until the scent was transferred I knew right away I had to give it a try (I saw this on a blog somewhere but I cannot remember the name of the blog or how I came to it, so if it was your idea I thank you very much).
We only had a grapefruit on hand so I tried that instead. E ate the grapefruit, I popped the peel in a jar, covered it with vinegar and left it for about 2 weeks. It definitely is grapefruit scented and...E still doesn't like the smell. ;-) Ah well, it pleases me that I have found another use for something and I'm all for grapefruit-scented bathroom mirrors and tubs.
