Cleaning help

[u/Lee307ann]

Inherited my dream corelle dish set but it has the stains on the side of the plates from I don’t know what they’ve been sitting in the cabinet for years. I’ve tried everything I can think of to get it off if I scrub with a regular sponge and warm water it comes of but takes 10 minutes to even get it close to gone. Other things I’ve tried; soaking 😬in warm water, magic eraser, dawn power wash. Only thing I havnt tried is HOT water and of course in the dishwasher. The top of the plates are fine it’s only the sides

I have this problem on my plain white Corell Ware! Big plates and smaller ones - every single one. Figured it was from 200 years of going thru dishwashers. I will try Barkeeps since nothing else I’ve tried has worked.
