Granted store bought carpet deodorizers aren't terribly expensive, the homemade variety is even more so! And you can control what goes into it...healthier and more versatile.
2 cups of Arm & Hammer baking soda
1/8 tsp each Vanilla and Almond extract
1 tsp Ground Cinnamon
See Use It Up! and you will understand where I got the inspiration for this scent combination: the smell of baking granola!
Since cinnamon has antibacterial and antimicrobial properties, it is somewhat sanitizing as well as deodorizing! The whole process took all of two seconds and now I have a good supply of smell-good for my carpets! I used a glass jar I had on hand (I'm starting to hoard them now, so many uses!) and popped holes in the lid with a hammer and nail. Instant shaker. Maybe vacuuming just got a little bit more interesting.
What scent combinations would you use for homemade carpet sprinkles? Any other container ideas?
