Hello Veldina,
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.
Please contact our customer service team at 1-800-775-0703 or customerservice@kraususa.com if you’d like to continue the conversation.
