Everyone loves a cup of coffee to kick start their day. After making that refreshing cup of coffee, most people will rinse off their coffee grounds down the drains. But do you know that is not the right way to dispose of used coffee grounds? Are you aware that used coffee grounds are not suitable for your drainage system?

Coffee grounds do not wash down the drains but clump together and stick on the drain pipes. With time, the coffee grounds clump together with drain sludge and form clogs on the drain pipes. Therefore, coffee grounds clog sinks over time.

This article will give you more in-depth knowledge on how coffee grounds clog sinks and how you can properly dispose of used coffee grounds. Read on to learn more.

Do coffee grounds clog sinks

The answer to this question is YES. Coffee grounds will most definitely clog sinks. The coffee grounds do not break down when washed down with water but clump together and stick to the existing sludge in the drains.

Coffee grounds are one of the main contributors to drain clogs in the kitchen. The grounds do not break up but instead, accumulate in the drains and eventually increase the drained sludge. The drain sludge, together with the clumped coffee grounds, clogs the drains.

Coffee grounds will clump together rather than break down, making it challenging to wash them down the drain. Unclogging a drain is a challenging task. However, there are several ways of removing the coffee grounds clogs from the drain. Read below to learn how.

How to unclog a sink clogged with coffee grounds

There is a myth that coffee grounds help to clean drains and make the drains smell fresh. For this reason, many people are still draining coffee grounds down the sink. With time, these people have to deal with drains clogged up by coffee grounds.

If you find yourself in this situation, do not worry because you can get out of it.

The first step should be to use a plunger. A plunger will release pressure build-up and force the clogs free. You can then use a snaking to push the clogs through and out of the drain. However, this method will not remove all clogs. Some coffee grounds might still be clamped to the drains. Use organic products or safe-food methods to clean out the remaining sludge and clumps.

To clean up the residual clogs, follow these steps:

  1. Pour a cup of baking soda into the sink.
  2. Follow up the baking soda with about half a cup of white vinegar.
  3. Put the sink plug to force the mixture down the drain
  4. Leave the mixture for about 60 minutes
  5. After an hour, pour boiling water down the drain.
  6. Repeat the process a few times if the drain is still clogged up.

After several tries, find a plumber to remove the coffee grounds clog professionally if this process does not work out. You can also request professional jetting, which will remove all drain clogs that have accumulated over time.

How to prevent coffee grounds from going down the drain

As we have already discussed, draining coffee grounds down the sink is not the best disposal method. So how do you prevent the coffee grounds from going down the drain?

The best way to prevent coffee grounds from going down the drain is to use a kitchen drain filter (Amazon link) It’s great for catching fairly coarse grounds from clogging your drains. You can also use a cloth to filter out the grounds. This method is simple, and you can save the coffee grounds for later use and protect your drains from clogs.

After filtering out the grounds, the next task is to dispose of the grounds safely.

How to dispose of coffee grounds

The easiest way to dispose of coffee grounds is by throwing them into the trash cans or coffee grounds knock box (Amazon link). However, there are more sustainable ways of disposing of coffee grounds.

For example, coffee grounds are nutritious to plants and a great addition to a compost pile. Throw the used coffee grounds onto the compost pile or use them as fertilizer if you have a garden. You can also use the grounds to mulch your house plants.

You can also reuse coffee grounds as opposed to throwing them as trash. There are several ways to reuse coffee grounds, but you cannot reuse them to make another cup of coffee. You can reuse coffee grounds as scrubbers to scrub off stubborn stains on pots and pans. Some people also use coffee grounds as an exfoliating scrub for their skin. Coffee grounds are also a great ingredient in making homemade dye.

Whichever method you use to reuse coffee grounds, make sure you keep the ground residue away from drains and sinks.

How to dispose of coffee grounds from the french press

It is quite a hassle to find the right way to dispose of coffee grounds. It is more of a hassle if you are using a coffee-making device such as the French press. Some coffee makers have paper filters that trap the grounds for easy disposal. But when you are using a French press, the grounds stick at the bottom of the press.

Many people rinse off the grounds from the press and into the drains. By now, it is clear that coffee grounds and drains are not a good mix, but if you still do this then i recommend getting a kitchen drain filter (Amazon link).

So how do you dispose of coffee grounds from the French press?

  • dismantle the plunger and the brewing chamber
  • fill up the brewing chamber with water making sure to rinse the sides of any residue grounds
  • swirl the chamber to dislodge coffee grounds stuck at the bottom
  • use a strainer or a filter to trap the coffee grounds from the brewing chamber
  • dispose of the coffee grounds using your preferred method.

How to dispose of coffee grounds from a reusable filter?

There are different types of reusable filters, such as those in the single-serve coffee baskets and the auto-drip coffee maker. The cleaning method is almost the same for all types of filters.

To dispose of coffee grounds from a reusable filter:

  • Empty the coffee grounds from the filter. Do not dispose of them through garbage disposal or drains. Reuse or use them in a compost pile and fertilize a garden.
  • Use a paper towel, towel, or sponge to wipe the filter.
  • Rinse the filter with warm water. If you can, pour the rinsing water into a bucket and use the water to water your flowers. Avoid as much as you can draining the water through the sink.
  • Soak the filter in vinegar and water. This will dissolve any remaining coffee grounds.

Always remember to clean your filter regularly.

Do coffee grounds clog garbage disposal

You should avoid disposing of coffee grounds down the garbage disposal systems. Garbage disposal systems are also vulnerable to clogs and system jams caused by coffee grounds. The fine texture of coffee grounds makes it difficult for the system to deal with coffee grounds waste properly.

Final Words

Some people have been draining coffee grounds down the sinks for many years without any problems. However, this does not mean you should do it. Over time, these grounds will block your drainage system, and you might be forced to replace your whole drainage system. Avoid the unnecessary risk, dispose of your grounds onto a compost pile or use them to keep your plants healthy.
