A:Answer Hi brenda.
Thank you for reaching out regarding your Samsung - 5.8 Cu. Ft. Self-Cleaning Freestanding Fingerprint Resistant Gas Convection Range if it is difficult to clean the grates on top of the range. Regarding your concern, it is not difficult to wash the grates; all you need is warm soapy water, and then rinse with clean water. If there is a lot of buildup or grease, soak them in hot water, a mild degreaser, or white vinegar for 15 to 30 minutes. When done cleaning, make sure the grates are completely dry before placing them back on the cooktop.
