Carpet cleaner. I used it and it works very well. You'd think with the peroxide that it would bleach the carpet out, but I was at that point with my carpet (it needs to be replaced but we don't have the $$$) where it didn't matter either way. It works! Then I went over it with my steam mop. My carpet definitely looks better!!!
In a small saucepan, cover orange peels and 1/2 - 1 tsp of cinnamon (or cinnamon sticks) with water. Bring to a boil then reduce heat to low and simmer, adding water as necessary. Tried this today with mandarin orange peels, cinnamon, and apple pie spice and it made the house smell so good.
