3.3 Using the Grill & Griddle
The reversible grill and griddle accessory can be placed over the center burner or two adjacent burners for grilling or griddling. Ensure it is properly seated on the grates before heating.
4. Care and Maintenance
Regular cleaning and maintenance will prolong the life and appearance of your cooktop.
4.1 Cleaning the Cooktop Surface
The 304 stainless steel surface is resistant to stain, heat, and discoloration. For daily cleaning, use a soft cloth with mild soap and water or a stainless steel cleaner. Always wipe in the direction of the grain. The QuickClean Base and sealed burners make it easier to manage spills and prevent food from accumulating in hard-to-reach areas.
4.2 Cleaning Grates and Burner Caps
The heavy cast iron grates and burner caps can be removed for thorough cleaning. Wash them with warm, soapy water. For stubborn stains, a non-abrasive cleaner designed for cast iron may be used. Ensure all parts are completely dry before reassembling them on the cooktop.
4.3 General Tips
- Avoid using abrasive cleaners, scouring pads, or harsh chemicals that can scratch or damage the stainless steel finish.
- Clean spills immediately to prevent staining.
- Regularly check burner ports for blockages and clean as needed to ensure proper flame.
