As the Tread is an open flame product, is it natural for this to tarnish a little over time and this is a normal expectation of the product.
You can, however, clean this in-between uses.
To do so, we recommend using warm soapy water or a non-abrasive bleach-free kitchen cleaning spray or wipes to clean the external parts of the oven.
DO NOT us any abrasive cleaning products or abrasive sponges/cloths.
To clean the stone, we recommend leaving this on full flame for 30-60 minutes, which will then burn off any residue on the stone.
