Anyone had success cleaning one up like this example?

It was between floor metal and the original under carpet heat/ noise padding, may have gotten wet too.

Not as thin as it looks, just in the missing areas. Can "almost" see the build details, but needs some help.

Someone told me some years ago they "might" come back if soaked in a isopropyl / water solution...(?)

Thanks....
