Best way to clean a ceramic kamado BBQ

A clean ceramic Kamado BBQ ensures better flavor, more stable temperatures, and a longer lifespan for your barbecue. Here you can read how to easily clean your Kamado.

We’ll explain how to clean your ceramic Kamado and what you should pay attention to while doing it.

Why is it important to clean your Kamado?

A clean Kamado is the foundation for stable and flavourful barbecuing. When ash, grease, and food residue build up, it can disrupt airflow, making it harder to properly control the temperature. It can also cause bitter smoke and off-flavours that you would rather not end up in your food. In addition, dirt accelerates wear on parts and can, over time, also affect the ceramic material as residues start to settle into its pores and edges. Regular cleaning therefore ensures that your Kamado performs better, remains safer, and lasts longer.

How often should you clean a Kamado BBQ

Not every session requires a full deep clean. With a bit of rhythm, everything stays under control.

After every BBQ: quickly clean the grill grate
Every few sessions: remove ash
1–2 times a year: thorough deep clean

Cleaning a Kamado grill grate

The grill grate is the part that comes into direct contact with food, so it also gets dirty the fastest. The most effective way to clean it is to first heat up the Kamado thoroughly so that stuck-on residue loosens. After that, you can easily brush the grate clean with a suitable grill brush. If needed, you can then go over it with a little oil on a cloth to protect the surface. It’s important not to use harsh cleaning agents, as they can seep into the material and later affect the flavor.

Removing ash

Ash may seem harmless, but it can seriously disrupt airflow.

Let the Kamado cool down completely
Remove the ash tray or scoop out the ash
Use an ash vacuum or ash scoop to get the remaining residue
Check that the air vents are clear

Cleaning the inside

The ceramic material of a Kamado is actually a self-cleaning champion.

Remove accessories such as grates and heat deflectors
Heat the Kamado up to about 350°C
Let it burn for 30–45 minutes
Then close everything and allow it to cool down slowly

Grease and residue disappear through a kind of heat “magic” and turn into ash. Never use water or cleaning agents, as ceramic is porous and can be damaged or start retaining odd odors.

Common mistakes

Scrubbing the ceramic too aggressively
Using water on the inside
Letting ash build up
Using a pressure washer like it's a garden hose

Conclusion

A BBQ cover is the final but essential layer of protection for your Kamado. It keeps out rain, dirt, and UV light, helping both the exterior and the ceramic material stay in better condition.

Make sure the Kamado has cooled down completely before putting the cover on, so no moisture gets trapped inside. A good cover simply extends the lifespan of your Kamado and keeps it in good shape between BBQ sessions.
