Unusual metallic or chemical odor from a new cooker during first uses.

Safety first: Ensure good kitchen ventilation during initial uses.

• Initial cleaning: Wash the inner pot, lid, sealing ring, and accessories with warm soapy water before first use.
• Burn-in cycle: Run a water-only cycle with a tablespoon of vinegar to help remove odors.
• Ventilate: Open windows or use a range hood during the first few cycles.
• Persistent strong odor: If the smell is chemical and does not diminish after several uses and cleanings, contact Cosori support; the sealing ring or other components may need replacement.
