I really don’t care if I damage Chrome… Firefox on the other hand… you better not touch that!

On the serious side though, yeah, sanding it down will damage the chrome. You might not get to the metal, but it will become less shiny and porouse, and more food will stick to that particular part in the future, and it will be harder to get off.

We have a product over here, it’s called Arris DeGrass, I don’t think you have that in the US… it’s a degreaser, but it’s extra strong, like you don’t use that without gloves, EVER!.. ask me how I know 😂. Most people use it for cleaning ACs and degresing engines around here. So, basically, find an engine degreaser and use that, that should work just fine. But make sure you wash down everything REALLY REALLY good afterwards.
