Hi, Kaleem! Thanks for reaching out with your concerns; we're sorry to hear you're having trouble with cleaning and the knobs! We recommend cleaning the stainless steel with hot, soapy water and a cloth. The use of harsh chemical or chloride cleaners may damage the finish and cause stains or discoloration. As for the knobs, we will be happy to help however we can! If you can't reach us by phone, we are also available by Live Chat on our website. The icon will appear on the right side of the screen when there is availability in the queue. All else fails, shoot us an email at socialcare@frigidaire.com and we will get back to you as soon as we can. ~Ashton
