How to Clean Your OXO Burr Grinder: A Comprehensive Guide
Cleaning your OXO burr grinder regularly ensures optimal performance and longevity. This guide will walk you through the simple process of disassembling, cleaning, and reassembling your grinder, helping you maintain consistent grind size and prevent buildup that can affect flavor and performance, all while extending the life of your appliance.
Why a Clean Burr Grinder Matters
Burr grinders, unlike blade grinders, use two abrasive surfaces (burrs) to crush coffee beans evenly, leading to a more consistent grind and better extraction. However, this process generates coffee oils and fine particles that accumulate within the grinder, impacting both its functionality and the taste of your coffee.
Cleaning offers multiple key benefits:
- Improved Grind Consistency: Accumulated coffee oils and particles can clog the burrs, leading to uneven grinding. Cleaning ensures consistent particle size, resulting in a more balanced and flavorful brew.
- Enhanced Flavor: Rancid coffee oils can impart a bitter or stale taste to your freshly ground coffee. Regular cleaning removes these oils, preserving the optimal flavor profile of your beans.
- Extended Lifespan: Buildup can strain the motor and other components, potentially leading to premature wear and tear. Keeping the grinder clean helps maintain its efficiency and prolongs its lifespan.
- Prevention of Stale Coffee Buildup: Coffee oils and particles can become rancid over time, leading to an unpleasant aroma and flavor in your coffee. A clean grinder guarantees that only fresh coffee goes into your brew.
The Cleaning Process: A Step-by-Step Guide
Cleaning your OXO burr grinder is a straightforward process that requires minimal tools and effort. Here’s a detailed guide:
Unplug the Grinder: Always disconnect the grinder from the power outlet before beginning any cleaning procedure. Safety first!
Empty the Hopper: Remove any remaining coffee beans from the bean hopper.
Disassemble the Grinder:
- Remove the bean hopper by twisting it counter-clockwise.
- Remove the upper burr. Depending on your model, this may involve lifting it straight out or rotating it to a specific position for removal. Consult your grinder’s manual for specific instructions.
- Remove the grind container.
- Remove the grounds tray.
Clean the Components:
- Bean Hopper and Grind Container: Wash these parts with warm, soapy water. Rinse thoroughly and allow them to air dry completely.
- Upper Burr: Use a brush (a soft toothbrush or a dedicated burr cleaning brush) to remove coffee grounds and oils from the burr. You can also use a dry cloth to wipe it down. Do not immerse the burr in water.
- Lower Burr and Grind Chamber: Use the brush to clean the lower burr and the grind chamber. A vacuum cleaner with a brush attachment can also be helpful for removing loose grounds.
- Grounds Tray: Wipe the grounds tray clean with a damp cloth.
Reassemble the Grinder:
- Ensure all parts are completely dry before reassembling.
- Reinstall the upper burr according to your grinder’s manual.
- Reattach the bean hopper.
- Replace the grind container and grounds tray.
Test the Grinder (Optional): Grind a small amount of coffee beans to ensure the grinder is functioning correctly after reassembly. Discard these test grounds.
Tools and Supplies You’ll Need
The cleaning process is very simple, and the tools needed are common household items.
- Soft brush (toothbrush or specialized burr cleaning brush)
- Warm, soapy water
- Clean, dry cloths

Common Cleaning Mistakes to Avoid
Avoiding these common mistakes will ensure you don’t damage your grinder:
- Using Water on the Burrs: Never immerse the burrs in water as this can cause rust and damage. Use a brush and dry cloth to clean them.
- Using Harsh Chemicals: Avoid using strong detergents or abrasive cleaners, as these can damage the grinder’s components and leave harmful residue.
- Reassembling Before Drying: Ensure all parts are completely dry before reassembling the grinder to prevent mold growth and damage.
- Forgetting to Unplug the Grinder: Always unplug the grinder before cleaning to prevent electrical shock.
Frequently Asked Questions (FAQs)
How often should I clean my OXO burr grinder?
You should perform a basic cleaning (brushing the burrs and wiping down the hopper and container) every 1-2 weeks. A deep cleaning with Grindz or a more thorough disassembly should be done every 1-3 months, depending on how frequently you use the grinder.
Can I put the burrs in the dishwasher?
No, absolutely not. Putting the burrs in the dishwasher will damage them and potentially render your grinder useless. Clean them with a brush and a dry cloth only.
What happens if I don’t clean my burr grinder?
If you don’t clean your grinder, coffee oils and particles will accumulate, leading to inconsistent grind size, stale or bitter-tasting coffee, and potential damage to the grinder’s motor and components.
How do I know if my grinder needs cleaning?
Signs that your grinder needs cleaning include uneven grind consistency, a bitter or stale taste in your coffee, slow or labored grinding, and visible coffee residue buildup on the burrs.
What is the best way to remove stubborn coffee oils from the burrs?
For stubborn coffee oils, consider using Urnex Grindz coffee grinder cleaning tablets. They are designed to remove residue that a brush alone may not reach.
Can I use compressed air to clean my grinder?
Yes, you can use compressed air to blow out loose coffee grounds from the burrs and grind chamber. However, be cautious not to blow particles further into the grinder’s internal components. Always wear eye protection when using compressed air.
My burr grinder smells bad. What should I do?
A bad smell usually indicates rancid coffee oils. A thorough cleaning with Grindz or a deep disassembly and cleaning of all components should eliminate the odor.
What type of brush is best for cleaning the burrs?
A small, stiff-bristled brush is ideal for cleaning the burrs. A toothbrush or a specialized burr cleaning brush with natural or nylon bristles works well.
Are there any specific models of OXO burr grinders that require special cleaning instructions?
While the general cleaning process is similar for most OXO burr grinders, it’s always best to consult your specific model’s user manual for detailed instructions and any model-specific cleaning recommendations.
Can I use rice to clean my burr grinder?
While some people use rice to clean their grinders, it’s generally not recommended. Rice can be too hard and may damage the burrs or leave behind starch residue. Grindz is a safer and more effective alternative.
What happens if I accidentally get water on the burrs?
If you accidentally get water on the burrs, dry them immediately with a clean cloth. You can also use a hairdryer on a low setting to ensure they are completely dry before reassembling the grinder.
Where can I buy Grindz coffee grinder cleaning tablets?
Grindz coffee grinder cleaning tablets are widely available online from retailers like Amazon, as well as in many specialty coffee shops and kitchen supply stores.
