How to Season, Clean, and Maintain Your Caldero Pot

A ceramic-coated aluminum caldero arrives factory-treated, but a light seasoning routine before the first cook builds a stronger nonstick layer and removes any manufacturing residue. The process takes less than fifteen minutes and sets the foundation for years of reliable performance.

Warm the pot gently over medium heat for two to three minutes, allowing the aluminum to expand evenly. Once warm, wipe the interior with a soft cloth dampened in neutral oil (vegetable or canola work equally well), distributing a thin, even coat across the entire cooking surface. Repeat this process two or three times, allowing the pot to cool between passes. This gentle repetition bonds the oil to the ceramic rather than creating a heavy, sticky film that becomes more burden than benefit.

Hand washing is non-negotiable for ceramic-coated calderos, not because the cookware is fragile, but because dishwashers expose the exposed aluminum handles and rim to sustained moisture and high heat, which degrades them irreversibly. A quick hand-wash routine takes less time than loading a machine and keeps the pot in flawless condition indefinitely.

Immediately after cooking, while the pot is still warm, rinse it under running water and use a soft sponge or cloth with mild dish soap to wipe away residue. Avoid scouring pads and abrasive scrubbers, which scratch the ceramic coating. For stubborn, stuck-on food, fill the pot with warm water and let it soak for five minutes; the residue releases cleanly without force. Dry the pot thoroughly with a kitchen towel, paying special attention to the handle and rim, which can rust if left wet. The right pan for rice deserves proper storage: keep it upright with its lid placed loosely on top, never nested inside another pot.

Calderos store best upright, exactly as they arrive from the manufacturer: the large pot standing on its base with the lid placed inverted inside it, and smaller pots set on top with their lids seated correctly. This arrangement prevents the handles from bearing weight and avoids the scratches and dents that come from nesting. If storage space is tight, lean the lids against the side of the pot rather than stacking them inside smaller vessels.

The silicone rim on the lid will absorb odors from aromatic dishes, especially heavily spiced foods like oxtails, mofongo, or seafood stews. This is a property of silicone itself, not a flaw in the cookware, and does not affect the flavor or safety of future dishes. If odor lingers, wipe the rim with a cloth dampened in white vinegar or leave the lid open to air overnight in a well-ventilated space. Some cooks also store the lid separately from the pot, removing it from the cooking vessel entirely before putting things away. When selecting the top pan for rice, consider how often you cook fragrant dishes, as the silicone rim's odor retention is one practical trade-off of the lid's heat-resistant design and ease of use.

Aluminum calderos conduct heat rapidly and evenly, making them excellent on gas and electric coil burners. However, they sit slightly heavier than stainless steel and can scratch glass or ceramic cooktops with repeated sliding. This is not a defect in the caldero; it reflects the aluminum's relatively soft surface and the delicate nature of smooth cooktop glass. Prevent scratching by lifting the pot straight up when moving it, never dragging it across the surface. Induction cooktops require a special approach: traditional aluminum calderos won't work on induction at all because aluminum is not ferromagnetic. Some manufacturers now produce induction-compatible models with steel bases, but these sacrifice some of the heat conductivity that makes calderos so responsive.

For maximum cooktop compatibility, match the burner size to the pot's base. A caldero sitting on a burner much larger or smaller than its footprint experiences uneven heating and may damage the stovetop surface over time. Position the pot so the flame or heat element touches only the aluminum base, never the handles or rim. The handles themselves conduct heat rapidly during cooking, so always use a kitchen towel, pot holder, or short oven mitt to grip them. This simple habit prevents burns and extends the life of the handles, keeping them from becoming weak or discolored from repeated contact with your bare skin.
