Save an old parmesan cheese container, and fill it mostly with baking soda. Then, dump it back out into a bowl. This is so it’s easier to mix everything up. Shaking it all up in the same container doesn’t distribute the essential oils as well. In the bowl, shake some dried cloves, dried nutmeg, and about 20-25 drops tea tree oil. Stir well, and pour back into the shaker container.
Shake onto carpets, leave sit for about 5 min or so, and vacuum. (I’m going to assume this would work well on furniture/mattresses as well, but I haven’t tried it yet.)
There truly are a ton of tweaks of this on the internet, so play around with it to get a scent/texture you like. Some people put cinnamon in as well, or skip the spices and just use essential oils they like, or just use plain baking soda. If you’ve got light colored carpets, you may want to forgo the dark spices. I’ve got a light-ish speckled berber, and it doesn’t show, but if I had all white, I might not want to risk it.
As for the base, baking soda is good at neutralizing odors, but there’s some info out there that it doesn’t play nice with hepa filters on vacuums. I’ve got an older vacuum that uses a bag, so I don’t have to worry about that. Basically, the baking soda’s powder is too fine and clogs up the hepa filter, I think. Other sites suggest using cornmeal instead of baking soda if you’ve got a vacuum with a hepa filter, but I haven’t tried it, so I can’t vouch for whether that works. I’m not sure if cornmeal absorbs odors the way baking soda does, or if it simply acts as a way to dilute and spread out the essential oil scent.
Also, some sites recommend adding borax to the mix as well. I would suggest a bit of caution for this. While borax does occur naturally in the environment (hence it’s “all-natural” label), that doesn’t necessarily mean it’s safe to use in high quantities around pets and children. It’s not good to breathe in, and it irritates eyes in powder form. While I use it in my laundry soap and to sprinkle in the toilet to clean it, I certainly wouldn’t want to use it in my carpet powder. To me, there’s a difference between diluting it in water to use it and using it straight from the box.
Anyone else have any good carpet freshening suggestions?
