Empty and rinse the carafe and filter basket after each brew

The fastest way to keep your OXO 8-cup coffee maker clean is to empty it while it's still warm, before coffee residue dries on the glass. Remove the carafe from the warming plate and pour out any leftover coffee. Rinse the inside of the carafe with hot water and wipe it dry with a soft cloth.

Next, open the top of the machine and lift out the filter basket. Discard the used filter and grounds, then rinse the basket under running water. The basket is dishwasher-safe, so you can also place it on the top rack of your dishwasher if you prefer. Let both the carafe and basket air-dry or dry them by hand before reassembling.

Key Takeaways

  • Rinse the carafe and filter basket with hot water when ready after each use to prevent dried-on coffee stains and buildup.
  • Run a cleaning cycle with white vinegar and water every one to three months to remove mineral deposits inside the machine.
  • The carafe, filter basket, and lid are all dishwasher-safe and can go on the top rack for convenience.
  • If your coffee tastes weaker or brews slower than usual, mineral buildup is likely the cause and a vinegar cleaning will restore performance.

Deep clean with white vinegar to remove mineral buildup

Over time, minerals from your tap water build up inside the heating element and water lines of your coffee maker. This buildup slows brewing, weakens the taste of your coffee, and can eventually damage the machine. You can remove it by running a vinegar cleaning cycle every one to three months, depending on how hard your water is.

Fill the water reservoir with a 1:1 mixture of white vinegar and water. Place an empty carafe on the warming plate. Turn on the machine and let it brew about halfway through the cycle, then turn it off and let it sit for 15 minutes. This pause allows the vinegar solution to soak the heating element. Turn the machine back on and let it finish brewing the rest of the vinegar solution into the carafe.

After the vinegar cycle is complete, empty the carafe and refill the reservoir with fresh water only. Run two full cycles of plain water through the machine to rinse out any remaining vinegar smell and taste. Your coffee maker is now clean and ready to use.

Wipe down the exterior and warming plate

The outside of your OXO coffee maker collects dust and occasional coffee splashes. Unplug the machine and let it cool completely. Use a damp cloth to wipe the exterior plastic housing, the power cord, and the base. For stubborn spots, dampen the cloth slightly more and rub gently.

The warming plate can develop coffee stains and mineral residue. Once the machine is cool and unplugged, dampen a cloth with a small amount of white vinegar and wipe the plate clean. Dry it when ready with a separate dry cloth to prevent water spots. Never immerse the warming plate or any electrical part of the machine in water.

Clean the spray head if water is not distributing evenly

The spray head sits inside the top of the machine and distributes hot water over the coffee grounds. If you notice that water is pooling on one side of the filter basket or not wetting the grounds evenly, the spray head may be clogged with mineral deposits.

Unplug the machine and let it cool. Open the top and look for the spray head—it is the small perforated piece inside the lid area. Soak a paper towel in white vinegar and press it against the spray head for a few minutes to soften any buildup. Use a soft brush or an old toothbrush to gently scrub the small holes. Rinse thoroughly with clean water and reassemble the machine.

Replace the water filter if your OXO model includes one

Some OXO 8-cup models come with a replaceable water filter cartridge that sits in the water reservoir. This filter reduces chlorine and odors from tap water and should be replaced every two months or after brewing about 60 pots of coffee, whichever comes first.

To replace it, unplug the machine and remove the water reservoir. Locate the filter cartridge—it usually sits in a holder at the bottom of the reservoir. Twist or pull it out, depending on your model, and discard it. Insert a new OXO water filter cartridge (available online or at kitchen retailers) and twist it back into place. Refill the reservoir with fresh water and run one cycle of plain water through the machine before brewing coffee.

Descale with a commercial descaling solution for stubborn mineral deposits

If your coffee maker has not been cleaned in a long time or your water is very hard, white vinegar alone may not remove all the mineral buildup. A commercial descaling solution designed for coffee makers can be more effective. Products like Dripkit or Cafiza are made specifically for this purpose and break down mineral deposits faster than vinegar.

Follow the instructions on the descaling product's label, as concentrations vary by brand. Generally, you will mix the solution with water, pour it into the reservoir, and run a brew cycle similar to the vinegar method. Let the solution sit in the machine for 15 to 20 minutes, then finish the cycle. Run two to three cycles of plain water through the machine afterward to rinse completely.

Troubleshoot common cleaning problems

If your coffee still tastes like vinegar after rinsing, you did not run enough plain water cycles. Run two more full cycles of fresh water through the machine and the taste should disappear. If the carafe has stubborn brown stains that do not rinse away, fill it with equal parts white vinegar and water, let it soak for 30 minutes, then scrub with a soft bottle brush and rinse well.

If the machine brews very slowly even after a vinegar cleaning, mineral buildup may be severe. Repeat the vinegar cycle a second time, or use a commercial descaling solution for stronger results. If the machine still brews slowly or leaks water, the internal heating element or seals may be damaged and the machine may need professional repair or replacement.

Frequently Asked Questions

Can I put the entire OXO coffee maker in the dishwasher?

No. Only the carafe, filter basket, and lid are dishwasher-safe. The main machine body, warming plate, and water reservoir must be hand-washed or wiped clean. Never submerge the electrical base or heating element in water.

How often should I clean my OXO coffee maker?

Rinse the carafe and filter basket after every use. Deep clean with vinegar or descaling solution every one to three months, depending on your water hardness. If you have very hard water, clean monthly. If you have soft water, every three months is usually enough.

What should I do if water leaks from the bottom of the machine?

First, make sure the carafe is seated properly on the warming plate and that the filter basket is closed securely. If leaking continues, the rubber seals inside may be worn or the water reservoir may be cracked. Try running a vinegar cleaning cycle to clear any blockages. If leaking persists, the machine likely needs repair.

Is it safe to use vinegar in my coffee maker?

Yes, white vinegar is safe and is the standard method for cleaning coffee makers. The vinegar smell disappears completely after you run two or three cycles of plain water through the machine. Never use other types of vinegar like apple cider or balsamic, as they can stain or damage the machine.

Why does my coffee taste weak even after cleaning?

Weak coffee usually means the water is not hot enough or is not staying in contact with the grounds long enough. If cleaning did not fix it, check that the spray head is distributing water evenly over all the grounds. You may also need to use slightly more ground coffee per pot, or switch to a finer grind.
