Making coffee at home comes with a mess

There is nothing like a good cup of coffee to start the day or sip later with some dessert. While making coffee at home is more cost-effective than daily trips to the local cafe for the 150 million java lovers in America, it does come with a mess. 

After brewing is complete, you are stuck with how to get rid of those messy coffee grounds. Saving money by drinking coffee at home should not result in killing your sink. Coffee grounds cause more blockage and clogs in sinks than anything besides grease.

Why You Should Not Put Coffee Grounds Down The Sink

Coffee grounds clump together and create a clog

Like many coffee lovers, I used to fall for the old wives’ tale proclaiming that our plumbing needed coffee grounds each day. Imagine my shock when I needed to make a quick trip to the corner store for a commercial drain cleaner.

Coffee beans are nearly rock hard before grounding. So their grounds are hard, too – just super tiny.

The garbage disposal can't further grind down the coffee grounds. Water can extract the caffeine-filled essence and color from the beans – not dissolve them.

Instead of washing away along with the discarded apple peels, grounds clump together, pack the drain and create a clog. Coffee grounds won’t damage your sink or pipes. They will just stay like an unwanted house guest and clog your septic system.

How To Unclog Coffee Grounds From The Sink

You can use natural products to unclog your sink

Do you want to avoid harsh chemicals and use natural products instead to unclog your sink? Raid your pantry for baking soda and vinegar. Since baking soda is alkaline, it is the best solution to organically clear coffee grounds from clogs.

You may want to grab your jar of vinegar with caution, though. First, make sure you don't mix vinegar with bleach unless you want to breathe toxic fumes. However, if you combine baking soda, vinegar, and 4 quarts of boiling water, you can clear your tough clog in around an hour.

Of course, you can go the more expensive route and call a plumber. He would use a snake tool to unclog the problem.

Why Coffee Grounds Are Hard To Dissolve

Look at it this way. Would you expect a ground-up diamond to dissolve in water?

No, you would have expensive dust. Coffee grounds are the mini-me version of rock hard beans.

Those same beans also release oils during brewing. Oil and water don’t mix, so breaking down coffee oils is no small task.

The Best Ways To Dispose Of Coffee Grounds

The easiest to get rid of your coffee beans is to avoid the sink and throw them in the trash. It is non-hazardous and can absorb nasty odors – perfect for the leftover bones on fish Friday.

Do you have a smelly fridge? Switch out the baking soda for a bowl of used coffee grounds. Coffee is great for eliminating odors.

Due to their high mineral content, you can use them to fertilize your garden. Tired of bugs eating your prize-winning cabbage, sprinkle the grounds anywhere you want to repel critters.

Since we are already in the garden, add some grounds to your compost. Plants absolutely love their high nitrogen content.
