I am the one who put the initial question.
Thank you for your advice, and I tried accordingly. Then, I realised my initial question was wrong.
I think I accidentally used ‘Power Cleaner Limescale & Shine’ on my stainless steel hob instead of ‘Power Cleaner Grease & Sparkle’. The latter is bleach blended cleaner, but the former one is to remove Limescale. (I have two Bang Cleaner and I think I used a wrong one.)
I tried bleach and brillo on the hob, but it did not work. Is there any other way to remove stain on stainless steel made from the Limescale remover?
If this is not possible, I would appreciate it if anybody could let me know where I could purchase just the surface of the cooker, as I cannot find anywhere online that sells just the surface component on its own. (we are renting the house, and I want to solve the problem at least possible price.)
Thank you again
