Coffee Ground Hacks We All Wish We Knew Sooner

Coffee grounds can be used in a variety of applications, from boosting the taste of your favorite foods to enhancing your hair color. Read on for some incredibly useful things you can do with the coffee byproduct.

We've all been there. Someone puts something in the refrigerator that smells very strong or inadvertently leaves something in there that ends up stinking up the whole appliance. While it's best to remove the offending food item, that still may not do the trick. Instead, try coffee grounds.

They contain nitrogen, which when combined with carbon can remove foul smells. The grounds actually absorb and eliminate odors. Simply put a bowl of grounds in the refrigerator, and they will do all the work.

Turn coffee grounds into compost, which makes a great fertilizer for your garden's plants. Studies have shown that compost that contains coffee grounds has more nutrients than compost without it. And the more compounds you use, the better quality it will be. Plus, it produces less greenhouse gas emissions.

If you want to make a nutrient-heavy compost, add the following items to the coffee grounds: grass clippings, leaves, eggshells, fruit and veggie trimmings, stale bread, and shredded newspaper.

Fleas are a nuisance because they are irritating to both you and your pet. While you can purchase several different types of flea-removal products from your local Walmart, they are made up of chemicals that you may want to keep away from your furry friend. Coffee grounds are a much better, natural alternative.

Shampoo your pet's fur, and then rub the coffee grounds all over his or her body. Then rinse the mixture off, and let the animal dry as normal. Just be sure your pet doesn't eat the coffee grounds because they can be toxic.

Even if you're a cat lover, furry felines can do things that are very upsetting. It is particularly aggravating when they choose to use certain areas of your home and garden as a litter box.

If your cat is notorious for urinating or pooping in your garden, there's a simple solution. Mix used coffee grounds with orange peels, and sprinkle the mix in areas that you want cat-free. This will prevent the cat from using your lovely landscaping as his or her own personal potty.

Everyone likes a tender piece of meat now and then (except for vegetarians, of course). However, sometimes you may end up with a steak with muscle fibers that make it a bit tough. If you want a softer texture, you'll need to tenderize it. You can do this with salt or coffee grounds.

The grounds have acids and enzymes that are perfect for getting the job done. You can also add used coffee grounds to a dry-rub recipe or rebrew grounds to make coffee and use it as a marinade.

Teenagers aren't the only ones who struggle with acne. It can be a problem for people of all ages. If you've tried all sorts of prescription medication, why not opt for a more natural alternative?

Coffee is chock full of antioxidants and contains natural astringents. This means it's perfect to use as a facial cleanser and toner. Mix the grounds with milk to make a paste. Rub it on your face, and let it sit for about 20 minutes before rinsing it off.

Dark circles under your eyes don't just look unappealing, they also make you look older. The skin is very delicate in this area, and it doesn't have much fatty tissue. To get rid of the puffiness and dark circles, consider using some coffee grounds, which are known to be high in antioxidants and full of caffeine.

Both of these ingredients have anti-aging benefits, which can combat under-eye circles. Specifically, caffeine has anti-inflammatory properties that promote blood circulation. And the antioxidants combat free radicals, which can cause aging. Add water or coconut water to coffee grounds to make a paste, and let it sit under your eyes for 10 minutes. Rinse if any irritation occurs.

Instead of using coffee grounds for regular outdoor composting, think about utilizing the spent grounds for vermicomposting. Unlike traditional composting, vermicomposting is done indoors in a contained environment, such as an old can. The resulting organic material can then be used to fatten up worms or other insects.

This process is also much quicker than traditional composting, so it's a good idea for those who don't utilize an extensive amount of whole foods in their day to day life!

Humans aren't the only ones who can benefit from the delicious nature of coffee. Houseplants can also utilize their properties. If you don't have an in-home composting system, adding spent coffee grounds directly to the soil of houseplants is a great way to give them a bit of extra life.

Since coffee grounds are nutritionally balanced and pH neutral, they're great slow-release fertilizer for indoor plants. Just top-off your fertilizer with the old grounds once every few weeks and watch as your plants begin to have an extra glow.

The old grounds will weight down the dough, allowing it to cook as though the filling is already in place.
