Weird circle on hotplates

[Downaski]

Hmm.. Not sure but it could be burnt-on food or grease that’s tough to clean off. Try using a cleaner designed for your stove’s surface—ceramic or glass cooktops often have specific products. Another option is to make a paste with baking soda and water, apply it to the stain, and let it sit for a bit before gently scrubbing. You might also find helpful tips in your stove’s manual. If these methods don’t work or if you’re worried about potential damage, reaching out to a professional could be a good next step.

Hello everyone !

Tonight after cooking dinner on the stove, I noticed a weird circle that was on the hotplate is used to cook. I though it was some dirt and I tried to clean it but it doesn't come off ! And when I touch it, it seems "rough", like the stove itself had burned.

Does someone know what it could be ?

Thank you in advance for your help !
