I have had this teapot about 3 months and in this last month it has been in constant use and yesterday these stains appeared, is it rust? Should I throw away the kettle or can it be saved?
Assuming it's stainless it might be rust or it could just be dirty. Just take a scotch Brite pad and scrub it off with some elbow grease. Even if it is rust it will come off and be fine. Source: metal trades person
Could be rust or some minerals that ended up on the bottom. Try boiling a mix of vinegar and water and see if it wipes off after. I'd keep using it anyways though, nothing to worry about.
I'm not a health expert, take this with a grain of salt. I'd be disappointed it was rusting, but also mostly shrug it off and keep using it unless it gets bad and flaky/scaley
Looks like it could be rust. Even if it it’s, that’s not really a problem. You can probably get rid of the rust by cleaning the teapot a bit better next time.
I don’t see any problem with continuing to use it in the future. If you’re worried about microbes colonizing the place, remember two things:
I find it amusing how no one points out how ridiculous it is for ops first reaction to 3 spots of brown in his brand new kettle is for him to throw it away and get a new one
