Does Coffee Eliminate Odors?

Coffee. Us enthusiasts say that it's the best drink in the world. The taste and smell of coffee heightens our senses. Drinking coffee can get us in a better mood. We enjoy exploring the different coffee beans and flavors.

Yet coffee is so much more than that. Did you know that it can remove odors? Yes, it can!

I've had a foul, lingering odor in my kitchen sink for the longest time. No matter how much I cleaned it or sprayed air freshener, the smell always came back. Until, one day, I started using coffee.

I'm writing this for coffee enthusiasts that want to learn more about coffee... or a frustrated someone that wants to, once and for all, remove foul odors. I'm going to explain the process, the best formula and preparation, and its benefits.

So let's get straight to it!

How Does Coffee Remove Odors?

Coffee is not only loved for its taste but also its strong and soothing smell. I won't enjoy my morning cups of coffee as much if it had no aroma.

This strong smell is enough to overpower any surrounding odors. Including garlic, onions, fish, puke, animal urine, dead animals, garbage disposals, etc.

The best part is that coffee doesn't mask the bad smell with a good one. That's not enough. It doesn't mask, it removes by neutralizing the odors.

I'm going to get a bit technical explaining how coffee can neutralize bad to horrible smells.

Whenever you smell something bad, sulfur gases are usually associated with it. So to get rid of the smell, you need to get rid of the sulfur.

On the other side, coffee has high levels of caffeine. We all know that. But did you know that caffeine has nitrogen?

To put it all together. Coffee releases nitrogen around the room when it's left outside. The nitrogen increases the carbon in the air to absorb sulfur gases. Once all the sulfur is absorbed, the smell of your room neutralizes. Meaning, there won't be any smell anymore.

I enjoyed thinking of coffee as a magical bean. But I was even more impressed when I understood the process of how it eliminates odors.

The Best Coffee Formula to Remove Odors

What's the best coffee formula for odor removal? Should the beans be whole? Fresh? Grounded? This is a question I've asked myself when experimenting in my lab... I mean, my kitchen. I'm sure it's a question you want answered, too.

Whole coffee beans work great in removing odors. But the best formula is coffee grounds. Used or unused. And fresh... always make sure it's fresh.

More nitrogen releases in the air with crushed coffee beans rather than whole ones. The more nitrogen there is, the more carbon can absorb sulfur gas. The more the odors will disappear.

It can get a bit complicated when deciding between used or unused coffee grounds, though. Both work wonders, no doubt. But both have some teeny-tiny downsides.

If you have used coffee grounds, then a lot of the caffeine and nitrogen are already dissolved in the hot water. If you have unused coffee grounds, then you might feel like wasting a lot of good coffee for the next day.

Personally, I hate seeing any good coffee grounds thrown away, especially if it's not yet used!

I got around this by having used coffee grounds for the bad smells. The remaining caffeine and nitrogen can handle that. And using unused coffee grounds for the horrible, reeling stenches.

I figured that I could sacrifice some fresh and unused coffee grounds for the good of my kitchen air. There's enough caffeine and nitrogen in unused coffee grounds for that.

How to Prepare Coffee Grounds

I know, by now, you're wondering how to prepare it. Great news, you can prepare it however you want!

That's probably not great news if you wanted some advice. Well, I'll tell you how I do it, in case you want to follow along.

I set the coffee grounds on pieces of toilet paper. I do this so that it can absorb any moisture. The moisture might get in the way of preventing full nitrogen release.

I then place the coffee grounds on a plate or bowl. Place that near the bad smell, in my case, the sink, and make it stay there overnight.

It's best to place the coffee grounds near the bad smell so that it concentrates on that area only.

If the whole room smells bad, then stuff a sock full of coffee grounds, tie it at the tip, and hang it up. That'll be able to absorb all the sulfur gases around the whole room.

It doesn't matter how you prepare it. Just make sure the coffee grounds have space to breathe... and also to keep it there overnight.

The Benefits of Using Coffee Grounds

To top it all off, using coffee grounds for eliminating odor is so beneficial.

There's always a pang of guilt whenever I throw used coffee grounds away. Especially because there's so many of them. I came up with a solution to never waste another coffee bean again!

First, I use it to make my delicious and soothing coffee. I then use it to absorb all the foul odors away. When all the nitrogens are removed, I use it as plant fertilizers.

Coffee is really a "jack of all trades".

Hello Fresh Air

Why don't we use air fresheners to remove bad odor? Before I discovered using coffee, I've been using a lot of air fresheners. But, like I said, it only masks the bad smells. Your air quality is still bad, though it smells so good.

Also, pretty soon, when the air freshener runs out, the smell will come back again. It's a never-ending story.

With coffee grounds, you can be certain that the air is fresh from sulfur gases. It not only removes the bad smells, it also makes your indoor air very fresh with its natural process.

Avoid Chemicals

Because coffee grounds remove odor in a natural way, you don't have to worry about chemicals.

I tried reading the ingredients to the air freshener I used to spray. I got a slight panic when I could hardly pronounce any ingredient. Too many chemicals. My family and I were inhaling too many chemicals.

I never had to worry about that ever since I started using coffee grounds, though. To me, it's the safest way to remove bad odor anywhere in your house, car, or office.
