What to check first

Brewer type and filter type

Know your machine. Is it a drip, espresso, pod, or something else? This matters for descaling. Paper filters are for drip, metal for some pour-overs. Dezcal works on most machines, but the process might vary.

Water quality and temperature

Hard water is the enemy of coffee makers. It leaves mineral deposits. Using filtered or bottled water is a game-changer. The right water temperature is crucial for extraction, but for cleaning, the solution temperature is key as per Dezcal’s instructions.

Grind size and coffee freshness

While not directly related to descaling, the grind size and freshness of your coffee beans impact taste. Old, stale coffee or the wrong grind can make your brew taste off, even with a clean machine. Freshly ground beans are always best.

Coffee-to-water ratio

Getting the ratio right ensures a balanced cup. Too little coffee and it’s weak; too much and it’s bitter. For descaling, you’re using a specific solution-to-water ratio, so pay close attention to that.

Cleanliness/descale status

When was the last time you descaled? If it’s been a while, or you’re seeing visible scale, it’s definitely time. A quick visual check of the water reservoir and spouts can give clues.

Step-by-step (brew workflow)

1. Empty the reservoir.

• What to do: Pour out any old water from your coffee maker’s water tank.
• What “good” looks like: An empty, clean reservoir ready for the descaling solution.
• Common mistake: Forgetting to empty it, diluting the descaling solution. Avoid this by doing a quick visual check.

2. Prepare the Dezcal solution.

• What to do: Mix Dezcal powder with water according to the package directions. Typically, it’s a specific amount of powder per quart or liter of water.
• What “good” looks like: A clear or slightly colored liquid with no clumps of powder.
• Common mistake: Using too much or too little Dezcal, or not dissolving it fully. This can make it ineffective or too harsh. Read the label!

3. Fill the reservoir with the solution.

• What to do: Pour the prepared Dezcal mixture into your coffee maker’s water tank.
• What “good” looks like: The reservoir filled to the appropriate line with the descaling solution.
• Common mistake: Overfilling the reservoir, which can cause leaks. Stick to the max fill line.

4. Place a large container under the brew head/spout.

• What to do: Position a carafe or large bowl to catch the hot descaling solution as it runs through the machine.
• What “good” looks like: A secure container that can hold the entire volume of the solution without overflowing.
• Common mistake: Using a container that’s too small, leading to a messy cleanup. Measure your reservoir capacity first.

5. Run a brew cycle.

• What to do: Start a brew cycle as you normally would, but without coffee grounds or a filter. Let the machine run about half the solution through.
• What “good” looks like: The solution flowing steadily through the machine into the container.
• Common mistake: Forgetting to remove coffee grounds, which can clog the machine during descaling. Always brew without coffee for descaling.

6. Pause the cycle and let it sit.

• What to do: Turn off the machine halfway through the brew cycle. Let the remaining solution sit inside the machine for 20-30 minutes (or as per Dezcal’s instructions).
• What “good” looks like: The solution is actively working on mineral deposits inside the machine.
• Common mistake: Skipping this soaking step. It’s crucial for loosening tough scale buildup.

7. Complete the brew cycle.

• What to do: Turn the machine back on to finish running the rest of the Dezcal solution through.
• What “good” looks like: The reservoir is empty, and all the solution has passed through the machine.
• Common mistake: Not letting the entire batch run through. Incomplete cycles mean incomplete descaling.

8. Discard the solution and rinse the reservoir.

• What to do: Pour out the dirty descaling solution from your container. Rinse the water reservoir thoroughly with fresh water.
• What “good” looks like: A clean reservoir free of any residual Dezcal solution.
• Common mistake: Not rinsing the reservoir well. You don’t want your next cup of coffee tasting like chemicals.

9. Run at least two full cycles with fresh water.

• What to do: Fill the reservoir with fresh, filtered water and run a complete brew cycle. Repeat this at least twice.
• What “good” looks like: Clear water flows through the machine, and there’s no lingering smell or taste of the descaling solution.
• Common mistake: Only running one rinse cycle. Multiple rinses are essential to remove all traces of Dezcal.

10. Clean external parts.

• What to do: Wipe down the exterior of your coffee maker with a damp cloth. Clean the brew basket and carafe.
• What “good” looks like: A clean machine, inside and out.
• Common mistake: Focusing only on the internal components and neglecting external grime. A clean machine looks and works better.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your coffee tastes bitter or off, then descale your machine because mineral buildup can affect extraction.
• If your coffee maker is brewing slower than usual, then descale it because a clogged heating element or water line is likely.
• If you have hard water, then descale your machine every 1-2 months because mineral deposits build up faster.
• If you use soft or filtered water, then you can descale every 3-4 months, but check for signs of buildup.
• If you notice white, chalky residue in your water reservoir, then descale your machine immediately because this is visible scale.
• If your espresso machine is sputtering or not reaching proper pressure, then descale it because scale can impede the pump and group head.
• If you’re using a single-serve pod machine, then descale it regularly because the small internal passages are prone to clogging.
• If the Dezcal instructions say to use a specific soaking time, then follow that time because it’s optimized for mineral removal.
• If you’re unsure about your machine’s specific descaling process, then consult your owner’s manual because different models have unique requirements.
• If you hear unusual noises from your coffee maker, like grinding or straining, then descale it because scale can cause mechanical stress.

FAQ

How often should I use Dezcal?

This depends on your water hardness and how much you use your machine. Generally, every 1-3 months is a good starting point. If you have very hard water, you might need to do it more often.

Can I use vinegar instead of Dezcal?

While vinegar can descale, it’s not always recommended for coffee makers. It can leave a strong, lingering odor and taste, and some manufacturers advise against it as it can potentially damage seals over time. Dezcal is formulated specifically for coffee machines.

What happens if I don’t descale my coffee maker?

Over time, mineral deposits will build up. This slows down brewing, affects coffee temperature and flavor, and can eventually lead to permanent damage to your machine, rendering it useless.

Is Dezcal safe for all coffee makers?

Dezcal is designed for most standard automatic drip coffee makers, espresso machines, and single-serve brewers. However, always check your coffee maker’s manual to ensure it’s safe for your specific model, especially for machines with specialized components.

How do I know if my coffee maker needs descaling?

Signs include slower brewing times, coffee not being hot enough, unusual noises (like sputtering or grinding), and visible white, chalky deposits in the water reservoir. A decline in coffee taste is also a big clue.

Can I use Dezcal in my Keurig or Nespresso machine?

Yes, Dezcal is generally suitable for most pod-based machines. Just follow the specific instructions for your machine type and the Dezcal packaging for mixing the solution.

What’s the difference between cleaning and descaling?

Cleaning usually refers to washing removable parts and wiping down the exterior to remove coffee oils and residue. Descaling specifically targets the removal of mineral buildup (scale) from the internal heating elements and water pathways.

How long does the descaling process take?

The entire process, including brewing cycles and rinsing, usually takes about 30-60 minutes, depending on your machine and how long you let the solution soak.
