With the house being closed up so much in the winter months, it can smell stale or sometimes even worse, like our big dog has been in the house all day.  However, I refuse to use chemical aerosol air fresheners. I know too many people that are sensitive to fragrance chemicals, and it may aggravate asthma or migraines. Twenty years ago, my husband showed me a really easy way to freshen the indoor air in the winter and fall.  The secret ingredient is cinnamon. Honestly, I don’t know where he got it, but I wouldn’t be surprised if it was something his mom used to do when he was a kid. All that is needed is a stove, a small pot, cinnamon, an orange or orange peels, and water.  I fill the pot about half full with water and then put in a couple of orange slices or peels and a teaspoon or so of cinnamon.  It is a great way to make use of oranges that have gotten a little shriveled.  Then I turn it on the lowest setting on my stove so it doesn’t quite simmer.  If I want it to last a little longer, I top it off with more water after an hour or so.  Eventually, it releases steam and warm cinnamon fragrance permeates the house.  Do you do this in your house or know of any good frugal variations?
