How do you get your kamado ready for autumn after the summer?

After a summer of heavy grilling, grease, ash and food residue are baked into your kamado. An autumn service has three steps: a deep clean, checking the gaskets, hinges and cast iron, and putting the kamado somewhere sheltered under a ventilated cover. That keeps the airflow open and prevents rust, odours and mould in the wet season.

  • Burn-out: 30 to 45 minutes at a maximum of 220 °C
  • First an hour slowly up to 100-120 °C to avoid cracks
  • Check and grease the gaskets, hinges and cast iron
  • Sheltered, dry surface and vents slightly open
  • Water-repellent cover with room for air circulation

Getting Your Kamado BBQ Ready for Autumn: Why Maintenance Is Essential

This guide offers a step-by-step approach to cleaning, inspection, weather protection and autumn grilling tips, so your kamado stays in optimal condition.

Why Kamado Maintenance Matters After Summer

Heavy use during the summer causes grease, smoke and food residue to build up inside your kamado. This not only affects the flavour of your dishes, it also reduces the efficiency of the BBQ. An end-of-season service extends its life, prevents autumn problems and minimises the risk of odours or mould caused by damp.

Tools You Need for Cleaning a Kamado

Make sure you have these items before you start servicing your Grill Bill kamado:

  • BBQ grill brush or scraper
  • Soft cloths or microfibre cloths
  • Lukewarm water, with soft soap if you like
  • Food-safe mineral oil
  • Silicone spray for hinges, bolts and nuts
  • Ash removal tool or vacuum cleaner
  • Drying cloths
  • Lukewarm water and a sponge
  • BBQ cover

Step 1: Deep Cleaning the Kamado After Summer Use

Start with a complete clean to remove summer residue and get your kamado ready for autumn. Follow these steps carefully:

Removing Ash and Residue from the Kamado

  1. Remove charcoal residue and ash by taking out the fire ring and firebox. Use an ash poker or a small vacuum cleaner.
  2. Check the air vents for blockages. Keep the bottom and top vents free of dirt for good airflow.

Cleaning the Cooking Grates on a Kamado

  1. Take the cooking grates out and scrape off baked-on residue with a sturdy BBQ brush. Apply a thin layer of oil to cast iron grates to prevent rust.
  2. Clean with a soft soap solution, but re-season cast iron grates afterwards to prevent rust.

Cleaning the Ceramic Interior of the Kamado

  1. Use a soft brush or plastic scraper for the interior; avoid abrasive tools to protect the ceramic.
  2. Carry out a burn-out by heating the kamado to a maximum of 220°C for 30-45 minutes to burn off residue. Then let it cool down. Warning: heat slowly to 100-120°C for an hour so that moisture in the ceramic evaporates gradually and cracks are avoided.

Cleaning the Exterior and Wooden Parts

  1. Wipe the outside with a soft cloth, lukewarm water and soft soap if needed. Grill Bill kamados have no pits where dirt can lodge, so this is quick work.
  2. Dry thoroughly to avoid staining.
  3. Clean the wooden handle and side tables with a damp microfibre cloth and soft soap. Treat with outdoor furniture oil for a longer life, or store the side tables in the shed.

Step 2: Thorough Inspection of Kamado Components

After cleaning, check every component to prevent problems during autumn.

Inspecting the Kamado Gaskets

  1. Check the felt or fibreglass gaskets between the lid and the base for wear, so the seal stays airtight.
  2. Replace worn gaskets.
  3. Glue loose sections back down with heat-resistant adhesive or sealant.

Checking the Hinges and Bolts on the Kamado

  1. Check the hinges and bolts are tight so the lid does not become heavy to open. Readjust the lid if necessary.
  2. Spray silicone spray onto moving parts to keep them smooth; avoid scented oils that affect flavours.
  3. Remove rust on metal with a cloth or soft brush and protect it with silicone spray.

Examining the Cast Iron Parts

  1. Check the cast iron top controller for rust.
  2. Sand rust away with steel wool and coat with linseed oil to stop it coming back.

Step 3: Protecting Your Kamado Against Autumn Weather

Autumn, with its rain and cold, calls for extra protection for your kamado.

Putting the Kamado in a Sheltered Spot

  1. Place it under a canopy or out of the wind and rain.
  2. Stand it on a dry surface such as stone or raised wood to keep ground moisture away.
  3. Leave the air vents slightly open for ventilation.

Using a Protective Cover for the Kamado

  1. Choose a well-fitting, water-repellent BBQ cover with room for air circulation to prevent mould.
  2. Inspect it regularly for damage, especially after storms. Remove the cover in strong winds to stop the kamado being blown over.

Practical Tips for Autumn Barbecuing with a Kamado

Your Grill Bill kamado is now ready for autumn; enjoy it with this advice:

  • Controlling the Temperature: cooler weather lengthens the warm-up time; avoid chimney starters to prevent thermal shock.
  • Choosing Autumn Dishes: ideal for stews, slow-cooked meat and vegetables such as pumpkin. Use the Dutch Oven for this.
  • Cold Smoking: perfect for cheese, butter, salmon or chicken at lower temperatures; try the cold smoking starter kit.
  • Keeping It Dry: open the lid as little as possible in the rain to avoid losing smoke and changing the flavour.

With these steps your Grill Bill kamado stays ready for seasonal grilling!
