We recently purchased a house which has an Alberene soapstone double laundry sink in the basement. It's in decent shape; I haven't found any leaks or cracks, though it only has cold water going to it right now. It's dusty and cruddy from years in the basement so I'd like to give it a good cleaning and bring it back to life. Has anyone had good success with theirs? I don't need it to be perfect as we'll still just be using it for a utility sink.

I have read the following advice online; does this sound good?

-Start with dish soap and water

-If necessary try Comet or a mild scrub

-Fine grit sandpaper for scratches

-Finish with a coat of mineral oil and re-coat as needed.
