A:
I'm sorry to hear there are marks on your cooktop. Please review page 19 of the user manual regarding the use of certain types of cookware, such as aluminum and copper, that could cause marks on the cooktop. Pages 35-36 offer remedies for removing marks and scratches. If, after considering these factors, you believe the marks on the cooktop are not the result of such cookware or burned-on residue, please call 800-SAMSUNG to speak with an agent who will be happy to assist you further.
Thank you,
Ms. Samsung
