Clean the OXO 9-cup coffee maker with a vinegar rinse and regular soap cleaning for parts.

I’ve cleaned dozens of coffee makers, including the OXO 9 cup coffee maker, and I know exactly what keeps it tasting fresh and working well. This guide walks you, step by step, through how to clean OXO 9 cup coffee maker parts, how to descale the machine, and how to avoid common mistakes. You’ll get easy routines for daily, weekly, and deep cleaning so your coffee always tastes its best.

Why regular cleaning matters for your OXO 9 cup coffee maker

A clean coffee maker makes better coffee. Oils and mineral build-up change flavor and slow brewing. Mold and bacteria can grow in damp parts if you skip cleaning. Regular care keeps the brewer working and extends its life.

I once let mineral scale build up in an OXO unit. The brew slowed and the coffee tasted flat. After a full clean and descale, the machine returned to full strength and flavor in one brew. Learning this saved me time and money.

What you need before you clean the OXO 9 cup coffee maker

Gather tools first. This saves time and prevents missed steps.

• White vinegar or a commercial descaler
• Mild dish soap
• Soft sponge or cloth
• Small brush or toothbrush for crevices
• Paper towels or a lint-free towel
• Clean water for rinsing

Keep filters and paper filters on hand if your model uses them. Also have a pitcher ready to catch rinse water. A soft brush helps with the shower head and small parts.

Step-by-step cleaning guide for an OXO 9 cup coffee maker

This section covers daily, weekly, and monthly care plus a deep descale routine. Follow these steps to learn how to clean OXO 9 cup coffee maker thoroughly.

Daily cleaning

• Empty used grounds and rinse the basket and carafe after each use.
• Wipe the outside with a damp cloth to remove splashes.
• Let removable parts air dry fully before reassembly.

Weekly cleaning

• Wash the carafe, filter basket, and lid with warm, soapy water.
• Use a soft brush to clean the shower head and crevices.
• Rinse parts well and dry before putting back.

Monthly descaling (or every 2–3 months in hard water)

• Fill the water tank with a 1:1 mix of white vinegar and water.
• Run a full brew cycle without coffee to let the solution pass through the system.
• Turn off the brewer and let the vinegar solution sit for 20 to 30 minutes.
• Run two full cycles with fresh water to rinse. If odor remains, run one more rinse cycle.

Deep clean for stubborn stains and build-up

• Remove any removable silicone seals and rinse them.
• Soak the carafe in warm water and baking soda for 15 minutes to lift stains.
• Use a soft brush on the shower screen and around the spray head.
• Replace any worn filters or seals as needed.

Tips for a safe clean

• Always unplug the machine before deep-cleaning or touching internal parts.
• Never submerge the base or plug in water.
• Use only mild cleaners. Strong chemicals can damage plastic and seals.

Cleaning the carafe, filter basket, and shower head

These parts affect taste the most. Clean them well and often.

Carafe care

• Rinse after each brew to remove oils.
• For stains, add warm water and a tablespoon of baking soda. Let sit for 10–15 minutes, then scrub gently.
• Avoid abrasive pads that scratch glass or plastic.

Filter basket and lid

• Remove grounds and wash with warm, soapy water.
• Use a soft brush to clear trapped grounds around hinges and seals.
• Check the mesh or screen for blockages and rinse until clear.

Shower head and spray area

• Run water through the shower head to flush out debris.
• If the shower screen clogs, use a soft brush or a toothpick gently to clear holes.
• For scale, soak a cloth in vinegar and wrap it around the shower area for 15 minutes, then rinse.

Troubleshooting and practical tips for best results

If your OXO 9 cup coffee maker shows issues, this checklist helps fix them quickly.

Common issue: slow brewing

• Likely caused by mineral scale in the water path. Perform a descale and run extra rinse cycles.

Common issue: odd tastes or odors

• Run a vinegar descale and follow with two or three water-only cycles.
• Clean the carafe and replace paper filters to rule out stale grounds.

• Ensure parts are dry and seated properly after cleaning.

Practical tips from experience
