I’ve always been told you shouldn’t use magic erasers on pitchers it makes micro abrasions that store and grow bacteria.

I wish there was a way to get the stains out but my store hasn’t found it if there is one :(

Never ever bleach them or use magic erasers. Not food safe! Restroom cleaner is for restrooms only. Both of those things will get you dinged big-time in an inspection and could cause the store to fail.
