Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and performance of your range.
Exterior Cleaning:
Clean the stainless steel exterior with a soft cloth and a non-abrasive stainless steel cleaner. Avoid harsh chemicals or abrasive pads that can scratch the surface.
Cooktop Cleaning:
The sealed burners simplify cleaning. Remove grates and burner caps after they have cooled. Wash with warm, soapy water. For stubborn stains, use a non-abrasive cleaner. Ensure all parts are dry before reassembling.
Oven Interior Cleaning:
The oven interior features a blue porcelain coating. Clean spills and splatters regularly with a damp cloth and mild detergent. For baked-on residue, use an oven cleaner specifically designed for porcelain interiors, following the product instructions carefully. Do not use aluminum foil to cover the porcelain area of the oven, as this can damage the finish.
