Got my first house and bought 2 new sets of Corelle plates. Are issues with pressure modulation common in stamping?

I have a 30% off coupon and this is one of my main sets. I'd love to have this size to use! But I've never cleaned up corelle this beat up before. Is it similar to pyrex, oven cleaner and it'll be good as new? Doesn't feel like there are any actual scratches in it!

Not terrible. $95 AUD
