Running the Clean Cycle on Your OXO Coffee Maker

Quick answer

• Run the clean cycle regularly. It’s key to good coffee.
• Use a descaling solution or white vinegar.
• Empty the water reservoir and coffee basket before starting.
• Follow the specific instructions for your OXO model.
• Don’t skip it. Your coffee will thank you.

Who this is for

• Anyone who owns an OXO coffee maker and wants better-tasting coffee.
• Folks who’ve noticed their coffee tasting a bit off, or brewing slower.
• People who want to extend the life of their appliance.

What to check first

Brewer type and filter type

Your OXO brewer is likely a drip machine. Most use paper filters, but some have reusable metal mesh ones. This matters for cleaning. Paper filters catch more fines, but a clean metal filter is important too.

Water quality and temperature

Hard water? That’s mineral buildup waiting to happen. If your tap water is rough, consider filtered water. For brewing, the water needs to be hot, but the clean cycle is about heat and solution working together.

Grind size and coffee freshness

While not directly part of the clean cycle, these are crucial for coffee taste. Too fine a grind can clog filters. Stale beans just taste bad, clean machine or not. Keep your beans fresh and grind just before brewing.

Coffee-to-water ratio

This impacts brew strength. For cleaning, you’re not brewing coffee, but the principle of proper dilution for your cleaning solution is similar. Too weak a solution won’t clean; too strong might be harsh.

Cleanliness/descale status

When was the last time you ran a clean cycle? If you can’t remember, it’s probably time. Signs include slower brewing, odd noises, or a funky taste. A clean machine makes good coffee.

Step-by-step (brew workflow)

This is for a general OXO drip machine. Always check your manual for specifics.

1. Empty and prep: Remove the carafe and coffee basket. Make sure no old grounds are in there.

• Good looks like: A clean, empty brew basket and carafe.
• Common mistake: Leaving old grounds. This just recirculates gunk.

2. Add cleaning solution: Fill the water reservoir with your chosen cleaning agent. For descaling, use a dedicated descaling solution per its instructions. For vinegar, a 1:1 mix of white vinegar and water is common. Don’t overfill.

• Good looks like: The reservoir filled to the “max” line with the solution.
• Common mistake: Using too much vinegar or solution, which can be harsh. Stick to recommended ratios.

3. Replace parts: Put the empty coffee basket back in. Place the empty carafe on the warming plate.

• Good looks like: Everything is seated correctly.
• Common mistake: Forgetting to put the carafe back. Coffee solution everywhere.

4. Initiate clean cycle: Locate and press the “Clean” or “Descale” button. Some models might require holding it down for a few seconds.

• Good looks like: The indicator light for the clean cycle comes on.
• Common mistake: Not pressing the button correctly or long enough. The cycle won’t start.

5. Let it run: The machine will heat the solution and run it through the brewing system. This takes a while, maybe 30-60 minutes.

• Good looks like: The machine is actively running, you might hear gurgling.
• Common mistake: Interrupting the cycle. It needs to complete to flush everything out.

6. Discard solution: Once the cycle finishes and the machine beeps or indicates completion, carefully discard the hot cleaning solution from the carafe. Rinse the carafe.

• Good looks like: The carafe is empty and rinsed.
• Common mistake: Not discarding the solution. You don’t want to drink that.

7. Rinse cycle 1: Fill the reservoir with fresh, clean water to the “max” line. Run a full brew cycle using just water.

• Good looks like: A full pot of clean water brews.
• Common mistake: Not doing enough rinse cycles. You need to flush out all traces of the cleaner.

8. Discard rinse water: Empty the carafe.

• Good looks like: The carafe is empty.
• Common mistake: Leaving the rinse water in the carafe.

9. Rinse cycle 2 (and maybe 3): Repeat steps 7 and 8 at least one more time. Some manuals recommend two or three full water-only brews.

• Good looks like: Multiple pots of clean water have been brewed and discarded.
• Common mistake: Only doing one rinse. Lingering cleaner taste is the worst.

10. Final check: Ensure the reservoir is empty and the machine is turned off.

• Good looks like: A clean, ready-to-go coffee maker.
• Common mistake: Leaving water in the reservoir long-term. Can lead to mold.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Skipping the clean cycle	Mineral buildup, slower brewing, reduced heating element efficiency, bad coffee taste	Run the clean cycle regularly (monthly or as per manual).
Using tap water in hard water areas	Faster mineral buildup, requiring more frequent descaling	Use filtered or bottled water for brewing and cleaning cycles.
Using the wrong cleaning solution	Ineffective cleaning, potential damage to machine parts	Use a dedicated coffee descaler or a 1:1 white vinegar/water mix. Check your manual.
Not completing the full cycle	Incomplete flushing of cleaning solution, leaving residue	Let the clean cycle run to completion. Don’t interrupt it.
Forgetting rinse cycles	Lingering taste of vinegar or descaler in your coffee	Always run at least two full brew cycles with fresh water afterward.
Using old or stale coffee beans	Poor flavor regardless of machine cleanliness	Buy fresh beans and store them properly. Grind just before brewing.
Using too fine a coffee grind	Clogs filter, causes overflow, can lead to under-extraction	Use a medium grind for most drip coffee makers. Adjust based on results.
Not cleaning the carafe and basket	Old coffee oils build up, making coffee taste bitter and rancid	Wash the carafe and brew basket with soap and water after each use.
Storing the machine with water inside	Can lead to mold or mildew growth in the reservoir	Empty the water reservoir after each use, especially if you won’t be using it for a while.
Using abrasive cleaners or scrubbers	Scratches surfaces, can damage heating elements or internal components	Stick to soft cloths and recommended cleaning solutions.

Decision rules (simple if/then)

• If your coffee tastes bitter or burnt, then run the clean cycle because old coffee oils and mineral buildup are likely the culprits.
• If your OXO coffee maker is brewing noticeably slower than usual, then run the clean cycle because a clog from mineral deposits is probably restricting water flow.
• If you live in an area with hard water, then run the clean cycle more frequently (e.g., monthly) because mineral buildup will occur faster.
• If you just bought your OXO coffee maker and it’s new, then you probably don’t need to run the clean cycle yet, but check the manual for initial setup instructions.
• If you notice white, chalky residue inside the water reservoir, then run the clean cycle immediately because that’s a clear sign of mineral buildup.
• If you’re using white vinegar to descale, then ensure you run at least two full water-only rinse cycles because you don’t want your coffee tasting like salad dressing.
• If the “Clean” or “Descale” indicator light is on, then run the clean cycle because the machine is telling you it’s time.
• If your coffee tastes weak or watery, then check your coffee-to-water ratio and grind size first, but if those are fine, then a clean cycle might help if the machine isn’t heating water properly.
• If you’re unsure about the cleaning solution amount, then check your OXO model’s manual because using too much can be harsh on the machine.
• If you hear unusual grinding or struggling noises during brewing, then it could be a sign of a clogged system, so run the clean cycle.
• If you’ve only used filtered water and your coffee still tastes off, then it’s time to clean the brewer itself.
• If you’ve run the clean cycle and the problem persists, then it might be time to contact OXO support or consider a deeper clean if your manual outlines it.

FAQ

How often should I run the clean cycle on my OXO coffee maker?

Most manufacturers recommend running the clean cycle every 1-3 months, depending on your water hardness and usage. If you notice slower brewing or a change in taste, it’s probably time.

Can I use regular CLR or other cleaners?

It’s best to stick to what the manual recommends. Dedicated coffee descalers or a 1:1 white vinegar and water solution are generally safe. Harsh chemical cleaners can damage your machine.

What happens if I don’t run the clean cycle?

Over time, mineral deposits will build up inside your coffee maker. This can lead to slower brewing, inconsistent temperatures, and ultimately, a decline in coffee flavor. It can also shorten the lifespan of your appliance.

Does the clean cycle use a lot of electricity?

The clean cycle involves heating water, so it uses energy, similar to a regular brew cycle. It’s a necessary maintenance step that keeps your machine running efficiently.

My OXO coffee maker has a “descale” button. Is that the same as the “clean” cycle?

Yes, for most OXO models, the “Clean” and “Descale” functions are the same. They are designed to remove mineral buildup. Always refer to your specific model’s manual.

How do I know if my OXO coffee maker needs cleaning?

Common signs include brewing taking longer than usual, a sputtering or struggling sound during brewing, or a noticeable change in the taste of your coffee – often tasting bitter or dull.

Can I use lemon juice to descale my coffee maker?

While lemon juice has acidic properties, it’s generally not recommended for coffee makers. It can leave a residue or odor that’s hard to remove. Stick to vinegar or dedicated descalers.

What’s the difference between cleaning and descaling?

In the context of coffee makers, these terms are often used interchangeably. “Descaling” specifically refers to removing mineral (calcium and magnesium) buildup, which is the primary reason for running a “clean” cycle.
