Is this possible to remove the non-stick coating to get a full stainless steel fyingpan?

We can apply a non-stick coating to a fully stainless steel item.

However, the reverse process—removing a non-stick coating to obtain a fully stainless steel product—is technically impossible.
Indeed, in order to apply the non-stick coating, we need to prepare the interior surface of the product so that the coating adheres properly.

This preparation involves sandblasting the surface to make it more adhesive.
Unfortunately, our polishing processes cannot remove this surface preparation.
Moreover, we do not apply a non-stick coating to a product that has already been treated, as it would become unusable.
