Hi KimberlyA,
Thanks so much for your feedback.
We are sorry to hear that you are experiencing these stains on your new sink. I assure you, they are not rust marks. Typically, when red spots appear on a Stainless Steel Sink like ours it is simply surface discoloration. This is usually taken care of permanently with a stainless steel polish and/or cleaner when used according to the directions of the cleaning product. Products such as Bar Keeper’s friend and a fine 3M Scotch Brite pad are both great options.
However, if you do not find that this resolves your issue entirely, please contact our customer service department directly at 1-800-775-0703 and refer to case # 297138 or email us directly at customerservice@kraususa.com so we can look into this personally.
Thank you for taking the time to leave your feedback. I look forward to the opportunity to remedy this situation.
