A good seasoning should withstand some pretty brutal punishment. And even if it doesn’t, you can easily reseason the pan which you’ll have to do from time to time regardless.

I season my cookie sheets the same way. I’ve put them in the dishwasher, hit them with those steel wire soapy things, used barkeeper’s friend, not much has taken the seasoning off once it’s on there.

Except for lemon juice. Lemon juice fucks it right up.

The glass cooktops are insanely scratch resistant. I use a metal scraper to clean mine.
