Unusual uses for coffee
"Make a sachet of ground coffee and leave in the back of the fridge for a few days, the sachet should help absorb some of the strong food odours and emit a pleasant coffee aroma."

Did you know that coffee has a life outside of being a tasty bevvy? Ask Mike Asaurus – he compiled the following list. So, next time save those beans and try these unusual uses for coffee out:
Coffee air freshner
You can easily make your own with a pair of ladies stockings and fresh ground coffee Asaurus suggests. Simply double-up the stockings, fill with coffee grounds and then tie off.
In the garden
Compost:
Spent coffee grounds can be mixed with lye to make a great composting agent, you can even throw in the coffee filter, too!
According to Asaurus worms in compost like to eat the bacterium that grows on the facets of coffee grounds, though the grounds themselves are a a food source it also adds grit to the worms’ digestive system allowing them to digest better.
Fertilizer:
Small amounts of coffee grounds can be added directly to top soil, especially on plants that like high acidity in the soil like azaleas or roses. According to Asaurus coffee is high in nitrogen, calcium, magnesium, potassium and other trace minerals, spreading around a thin layer of coffee grounds on your soil will allow a slow release of these minerals into your plants.
Be aware of which plants like acidic soil (roses), and which plants don’t (tomatoes).
Insect Repellant:
Coffee has a very strong odour which many insects and animals do not like. In addition, it’s been suggested that mosquitoes, ants, slugs and maggots all dislike the acidity of coffee and will stay away from areas where there is high concentration of acidic soil Asaurus said.
Pet repellent
Pesky neighbour’s cat or dog always up in your flowerbed? Sprinkling coffee grounds along with other powerful odour-emitting substances can keep those animals away Asaurus said. “Most animals’ sense of smell is much greater than ours, and while coffee that may smell great to us can smell very unpleasant to a hyper-sensitive-olfactory feline,” he said.
According to Asaurus used coffee grounds can be mixed with orange peels (or other citrus) and spread around flowerbeds for an inexpensive pet deterrent.
Palate cleanser
You may have noticed that many perfume counters at department stores have a small dish of coffee beans nearby. According to Asaurus these coffee beans are there to ‘cleanse your palate’ (olfactory). The reason you want to smell coffee beans between perfume samples is that when testing out powerful aromatics it can get hard to discern one scent from another Asaurus said. According to him the strong odour of coffee beans excites different areas in your olfactory, allowing a more sensitive smell for the next perfume you want to smell.
Fridge deodorizer
According to Asaurus coffee can be used to help reduce refrigerator odours and food prep smells, like onions or other strong smelling food.
“Make a sachet of ground coffee and leave in the back of the fridge for a few days, the sachet should help absorb some of the strong food odours and emit a pleasant coffee aroma.”
Meat rub
Try a coffee rub on your next steak dinner for a unique flavour experience, Asaurus suggests! “I toasted fresh coffee grounds under a hot broiler for about 30 seconds, shaking often to prevent burning. The toasted coffee was then added with other steak spices and rubbed into the steak and left to marinate for a few hours in the fridge.”
Cook steak as desired.
Fabric dye / wood stain
Coffee’s dark colour makes it a good choice for giving fabrics that worn-look and wood an aged patina. According to Asaurus you are not going to end up with a very dark dye or stain, but you will get a unique, weathered look. Depending on number of applications and type of material the coffee is applied to this method of dying and staining can produce some effective results.
Fabric Dye
Brew a regular pot of coffee and completely immerse the fabric of choice into pot, you may need to place a small weight on top of the fabric to stop it from poking out of the coffee while it’s soaking, Asaurus suggests. Allow fabric to dye for 24 hours (or longer), then rinse fabric and let air dry. The result is a browny, off-white colour; giving the fabric an aged look. Try a few different strength of coffee brews, or length of time fabric is submerged to achieve different shades.
Wood Stain
Brew a strong pot of coffee and place the grounds back into the pot, allow to slightly and then apply to untreated wood. The coffee will stain the wood a slightly darker stain, but don’t expect very dark results. Leaving the coffee grounds directly on the wood will result in a darker stain.
Paint:
Artists and crafters have used coffee and tea as a form of ‘paint’ for ages. According to Asaurus regular brewed coffee can be brushed onto cardstock and will dry with a faded, brown, textured look. With repeated applications you can build up your image and create depth.
Cleaning abrasive
Used coffee grounds can be used as a cleaning abrasive according to Asaurus. Simply save up your coffee grounds and scoop some into your next dirty pot or pan before hand washing, the absorbent grounds are perfect for greasy pans and the small jegged edges of each ground helps in cleaning even the grossest of dishware.
Facial exfoliant / faux beard
Facial Exfoliate
Coffee grounds are abrasive enough to scrub with, but are soft enough to be used on your face he says. “Gently massage a small amount of spent coffee grounds into your face to use as an exfoliate. The sensation was like rubbing sand into my face, and not unpleasant. My skin was left feeling smooth, tingly with an espresso aftershave aroma”, he said.
Faux Beard
Feel free to get carried away and give yourself a fearsome coffee-beard while you’re doing the exfoliation.
