Learn the right way to clean your Gozney pizza oven stone without damaging it, plus when to replace it with a genuine Dome Gen 2 Stone Replacement Kit.
Quick answer
Clean your Gozney pizza oven stone by burning off food residue at high heat, then scraping away ash with a brass brush. Never use soap or water on the stone. If the stone cracks or chips, replace it with a genuine Gozney Dome Gen 2 Stone Replacement Kit to maintain even heat and safe operation.
Why oven stone care matters
The stone in your Gozney pizza oven absorbs and radiates heat evenly, giving you that crispy Neapolitan-style crust. Over time, food drips, flour, and grease can burn onto the surface, creating uneven spots that affect cooking performance. A well-maintained stone also prevents smoke and off-flavors from old residue.
Porcelain or cordierite stones like the one in Dome Gen 2 are durable but not indestructible. Thermal shock from sudden temperature changes or liquid spills can cause cracks. That's why the cleaning method matters as much as the frequency.
What you'll need
You don't need special chemicals. A brass-bristle brush (or a stiff nylon brush for gentle cleaning), a dry cloth or paper towel, and a metal scraper for stubborn bits are enough. Avoid steel wool or abrasive pads that can scratch the stone surface.
Step-by-step cleaning process
- Burn off residue at high heat: Fire up your Gozney oven to its maximum temperature (around 950°F / 500°C) for 20–30 minutes. This carbonizes any stuck-on food, turning it into ash that's easy to remove. Common mistake: leaving the oven on high for too long can stress the stone. Stick to 30 minutes max.
- Scrape away ash and debris: Turn off the oven and let it cool slightly until the stone is warm but not scorching. Use a brass brush or a metal scraper to gently push ash and charred bits into the oven floor, then sweep them out with a dry cloth or a dedicated oven brush. Checkpoint: never scrape aggressively with a metal tool on a hot stone — it can gouge the surface.
- Wipe with a dry cloth only: For any remaining dust, use a clean dry microfiber cloth. If you see greasy spots, repeat the burn-off step instead of wiping with water or detergent. Common mistake: using soap or water. Liquids seep into the porous stone and can cause cracking during the next firing.
- Inspect for damage after every 10–15 uses: Look for hairline cracks, chips, or areas where the stone feels uneven. A cracked stone can trap moisture and expand during heating, leading to larger breaks. Next step: if you spot any damage, order the Dome Gen 2 Stone Replacement Kit and follow the included instructions for a safe swap.
