Remove the ashes from your fire pit after they have become completely cold. Use a small whisk broom and dustpan. Do not let the ashes remain in the fire pot because they may foster deterioration, such as rust if the fire pot is made of metal. The fire pot can be made of other non-flammable material, but the ashes could damage it as well
Keep your fire pit covered when you are not using it. Use a canvas or other heavy cover manufactured specifically for your fire pit. Wait until the fire pit is completely cold before putting on the cover.
Store your fire pit in a shed or garage during the winter season when you are not using it. This will prevent degradation of the fire pot and the grout used on the ceramic shelf. Keep the cover on it while it is in storage.
Scrub the ceramic shelf periodically with a stiff-bristle brush and tile cleaner of a neutral pH diluted with water. Neutral pH is 7.0 on the pH scale and is neither acidic nor alkaline. You also can use a mild soap and water solution. Wipe the shelf dry with a clean cloth. Do this weekly or monthly, depending on how often you use your fire pit.
Use a spray-on tile cleaner and soft cloth to wipe up small spots between cleanings. Do this especially if food or drink spills onto the ceramic shelf, such as from toasting marshmallows.
Repaint the metal pot of your fire pit every year or so if it is painted. Do this more often if the paint begins to flake off. Consult the manufacturer for the type of paint required.
