11 Good Reasons Why Coffee Grounds are Worth Keeping

Coffee Ground

After brewing coffee, coffee grounds are often tossed into the trash bin. Some people regard the group of squeezed coffee beans as worthless items. If they only knew the alternative uses for coffee grounds, they would probably store the used beans in their cupboards.

Coffee grounds have many other uses aside from producing coffee. They can be used for gardening, repelling insects, and even as pet grooming products. Just by using these supposed waste products, the need to buy some household products can be instantly eliminated. Best of all, the use of coffee grounds is environment-friendly. You better think twice if you plan to throw away your next batch of coffee grounds. Here are 11 of the best reasons why used coffee grounds are worth keeping:

  1. Compost Material – Coffee grounds fit the standards set by gardeners for compost materials. The grounds, when mixed with soil, release nutrients that make the ground richer and more acidic. Plants that flourish in acidic soil will be healthier since they can get the needed nourishment from the ground. If you have a good supply of coffee grounds, just spread them evenly in your garden. Your plants will reward you by producing robust blooms.
  2. Pet Grooming Solution – Mix coffee ground extract with some water and the result is a nice grooming solution for pets. After a few rubs, the solution softens your pet’s fur, giving it a nice sheen. Some people even claim that the solution keeps fleas and other parasites off your pet, though it still needs testing for it to be considered a fact.
  3. A cutie cat

  4. Fridge Deodorizer – Storing different types of food inside the fridge can produce a nasty mixture of odors. Remove those pungent smells with a bowl filled with coffee grounds. Place the bowl inside your fridge and your coffee ground deodorizer will gradually absorb all unwanted scents. If your fridge is packed with stored food, just add more grounds and a few drops of vanilla to your deodorizer so that it can absorb more odors.
  5. No Place for Pet Litter – You can keep your pet from defecating in your garden if you spread a mixture of coffee grounds and orange peels around the area. Your pets will find the scent of the mixture too exotic for their defecating standards.
  6. A man with coffee grounds on his faceSkin Exfoliant – Rubbing your skin with coffee ground extract seems silly but it is actually a good idea. The extract removes dead skin cells, which results in better-looking skin. It can save you hundreds of dollars since this simple product can practically replacesseveral pricey sessions with your dermatologist.
  7. Shoe Deodorizer – Active people and smelly feet are often associated with each other. Break away from the norm by placing used coffee grounds in your shoes. It will not relieve you of foul-smelling feet, but it will certainly get rid of the evidence. Now, if you want to truly remove foot odor, you can always wash your feet with water and coffee ground extract.
  8. Hair Shine Solution – Let’s face it, everyone wants to have shiny and bouncy hair. Some people spend significant amounts of cash just to make their hair look better. You can look no further than your supply of used coffee grounds to give you softer and shinier hair. Just wash your hair with the coffee byproduct and rinse. You will soon sport your favorite celebrity hairstyle after a few strokes.
  9. Brushing her shine long hair

  10. Ant Repellent – Ants can be annoying, especially if they manage to make their way to your bath towel or clothes. You can avoid these tiny pests by rubbing coffee grounds on your closet. For some reason, ants dislike the scent and the properties of coffee ground extract.
  11. Fireplace Dust Regulator – Fireplace dust is always a big obstacle for someone who cleans the fireplace. Large dust formations can sting your eyes and irritate your sinuses. They can also make the surrounding areas dirty. To properly regulate dust, you can toss a handful of wet coffee grounds in your fireplace after operation. The wet grounds will hold the dust in place, lessening the appearance of dust clouds when cleaning the fireplace.
  12. Heating it up

  13. Coloring Ingredient – If you combine coffee ground extract with hot water, you can create brown dye for fabrics, art works and other applications. You can also mix the extract with henna to produce brown-colored henna tattoos.
  14. Scratch Remover – Coffee ground extract can erase scratches after several forceful scrubs. Its thick slippery base, when coupled with a rug, topples the foundations of most scratches. The scratches eventually fade in the process.

You can use coffee grounds as unconventional product substitutes for many household activities. With their wide variety of uses, you can say that they’re even more useful than their ungrounded counterparts.

    This is a great article, but I’m confused about one thing. What exactly is “coffee ground extract” and how do you make it? do you mean the grounds themselves. or do you run more hot water over the used grounds?

  2. rick on August 22nd, 2008

    I think I\’ll keep putting mine in my compost pile. It makes the birds fidgety.

  3. Paul on August 22nd, 2008

    I believe coffee ground extract is…the mixture of coffee grounds and water (usually hot water)…The resulting solution is the extract…

  4. quidpro on August 22nd, 2008

    Coffee ground extract would be…coffee?

    Coffee grounds + egg shells = no blossom rot on tomatoes!

  7. Wade Morris on August 23rd, 2008

    Coffee grounds are NOT acidic. This has been debunked. Coffe beans are acidic but the the acidity is removed by the brewing process.

  8. Scott on August 24th, 2008

    Wade- a small amount of acidity remains in the grounds after brewing. The pH of the grounds depends on the temperature of the water used, the length of time the grounds were exposed to the water and the grind of the beans. Smaller grinds give greater surface area which results in more of the acidity being leeched during brewing. It also depends on the qualities of the water used to brew as in how basic/acidic is it? How hard/soft? What other elements/compunds are in it, etc.

    Fun stuff- however I would be careful using coffee grounds on pets or in areas pets can get to. I\’ve treated more than one animal for coffee toxicity. In mild form is just hyperexcitability, but as the dose increases you can see arrhythmias and seizures. The most common presentation is a goofy young lab who ate ground out of the trash or the garden when someone is composting with coffee.

  10. Stevi on August 24th, 2008

    I also don\’t recommend using coffee grounds as an exfoliant, it leaves brownish orange stains on your skin.

  11. Jim on August 25th, 2008

    DO NOT use coffee grounds on a cats hair. Coffee is poisonous to cats in bean or liquid form.

  12. kilo on August 25th, 2008

    coffee ground exfoliant will also clog your bathroom drains. that\’s why the best exfoliants — salt, sugar — dissolve.

  13. ShawShaw on August 25th, 2008

    Yikes! Caffeine is very toxic to cats and dogs! Tip #2 doesn\\\\\\\’t sound like a good idea to me.

  14. Joe on August 25th, 2008

    Umm… is it April Fool’s Day? You can’t be serious.

  15. Karyn on August 25th, 2008

    I wouldn\’t use this on my blond hair either, for fear of loosing the color I pay so much to get.

  16. doug wells on August 25th, 2008

    worst article… ever.

  17. Andy on August 25th, 2008

    So, I put a bunch of coffee in my shoes.

    Upside: They don\’t smell anymore.
    Downsite: My shoes are full of coffee.

  18. April on August 25th, 2008

    Also great for cleaning cast-iron skillets! The grounds are abrasive, the oils keep the skillet cured, and the mild acids help cleaning.

  19. Jacquie on August 25th, 2008

    Little known fact: you can use coffee grounds to create a non-toxic, very effective roach trap:

    1. Place fresh, used coffee grounds in open glass jar.
    2. Add a few inches of warm water; mix.
    3. Add a strip of duct or masking tape down the side of the jar, vertically (so the roach can climb into the jar).
    4. Place jar overnight in roachs’ favorite hang out (kitchen, bathroom, etc.).

    Cockroaches love the smell of coffee grounds. They will climb into the jar and drown in the water. I think I learned this trick on Animal Planet or the Discovery Channel. I have tried it on several occasions and it worked very well.

  20. anonymouse on August 25th, 2008

    I beg to differ. I find some of the tips useful. I did use it on my hair and it became shinier than what I originally expected. I\’m about to use it as an exfoliant later, given its effects on my hair. The grounds\’ efficiency as compost material has been documented. I just had to get over the initial shock value of the info before i actually appreciated the true benefits of used coffee grounds.

    or you can use salt which does the same thing for cast iron but will NOT clog your drain. I have seen a coffee clogged drain.. its not pretty.

  23. Gus on August 25th, 2008

    Do not use any caffeinated products on your animals, used or not. Used coffee grinds still contain caffeine, which is HIGHLY toxic to cats and dogs.

  24. 7b on August 25th, 2008

    This list is 92% useless (or worse yet: dangerous). Spot on in re: compost, however.

  25. anonymoose on August 26th, 2008

    Not entirely useless. It is a decent exfoliant, compost material, and hair shine solution. I just got rid of the initial shock value before trying it out.

  26. Aakash on August 26th, 2008

    What about tea? Does it offer the same benefits, or is it just coffee?

  27. Jimmee on August 26th, 2008

    Well then maybe I will forward this article to my local Starbucks and they can start a whole new line of products with its used coffee grounds.
    Personally, I think this article is booooooo-guss!
    I think I will keep putting my used grinds down the sink.

  28. johnnypanda on August 27th, 2008

    Most of these are urban legends, placebo effects, and stuff that was made up to fill yet another attention-seeking blog. Let me guess, you guys submit this digg and stumbleupon yourselves?

    Next time try doing a little research before claiming this is true. You could end up hurting some innocent pets :(

  29. gah on August 29th, 2008

    gah! don\’t put coffee grounds in the sink (especially if you don\’t have a garbage disposal); it will clog.

  30. dimack on September 11th, 2008

    My grandmother always put HOT used coffee grounds down the sink drain. She said it picked up any fats on its way down the pipes. She never had a kitchen sink drain clog in all her 87 years. I have been putting HOT USED coffee grounds in my sink all of my life as well and I am 63 now. I have NEVER HAD A KITCHEN SINK CLOG either!

  31. dd on September 13th, 2008

    it’s on the internet, so it MUST all be true!!!!

  32. Joey on September 13th, 2008

    Yay! Let’s go for the bashing bandwagon. It makes us feel cool and rational.

    Okay, returning to the topic, I agree with number 8. I actually use coffee grounds as an insect repellent. It’s surprisingly effective.

  33. How to Green the Coffee , coffee ground exfoliant will also clog your bathroom drains,

    That is cool!

  38. Sean on April 19th, 2009

    Hmmm…maybe just decaf for the pets? I have heard that coffee grounds are helpful in the septic tank promoting the growth of helpful bacteria.

  39. Kimmy on May 2nd, 2009

    I have more than several times heard that coffee grounds are good for rubbing your thighs for cellulite… haven’t tried it, didn’t want to be the first known idiot w/ stained spots all over the restroom.. 8-)

  40. Davina on May 22nd, 2009

    doesn’t sprinkling coffee grouds over your garden attract cockroaches?

  41. belen on June 18th, 2009

  43. tonytran on July 5th, 2009

    Believe or not ‘coffee ground’ has been a replacement source of my VIARGA.

  44. dustin on July 25th, 2009

    I am a male. The coffee grinds work good as an exfoliant. I also use tea grinds, esp green tea. I’m 34 yrs old and people think I’m 25 because I take care of my skin. And no I’m not gay, I just care about my health.

  45. georges on August 8th, 2009

    The article is pretty good, but most of these recommendation are just plain crazy.

  46. bmgmom88 on August 10th, 2009

    if there is so much concern about the pets and the sink drains and the skin maybe we should just stop drinking COFFEE all together!!!

  47. warmonger on August 16th, 2009

    lol. let’s all drink to that

  48. norwayboy on October 16th, 2009

    Lukewarm(body-temperature) coffee is a great cleansing agent used in colonics.

  49. coffeenut on November 7th, 2009

    coffee extract IS coffee…just highly diluted…and the article says “coffee extract and add water”… totally dumb!!!!!
