I’m mid brew and just noticed this strange buildup on the lid of my kettle. I tried soap, soft scrub, and barkeepers friend and nothing can get it off (though it was brown and is now less so). What is this? Any tips on how to get it off?
Could it have been rust from somewhere else, that dripped on it, perhaps?though it was brown
If BKF doesn't remove it, it's probably etched. Does it feel rough-ish?I tried soap, soft scrub, and barkeepers friend
I don’t believe it’s rust but I guess it could be. It’s the cheap kettle that came with my first starter kit, so i think aluminum.Could it have been rust from somewhere else, that dripped on it, perhaps?
Is that the inside of a kettle lid? Stainless steel?
It does feel a little roughIf BKF doesn't remove it, it's probably etched. Does it feel rough-ish?
Look at it through a magnifying glass.
I don’t think soAny chance it could have been Chlorine (bleach) that leaked onto it?
Or some other corrosive (to stainless steel) product?
That’s what I figured—it’s not like the wort really touches the lid anyways, especially post boilBut... I doubt that "corrosion" is going to harm anything. Just keep it clean.
That lid is waaay too shiny to be aluminum.so i think aluminum
Yeah, just keep it clean (and shiny) and an eye on it.That’s what I figured—it’s not like the wort really touches the lid anyways, especially post boil
Aluminum self-oxidizes in air. It's the oxide that provides protection to the metal underneath.Could easily be an aluminum lid - I have one with a lid that bright that we use for steaming lobsters - in which case that could be corrosion.
Got a magnet?
So would the recommendation be to BKF it until it comes off? Any other tips to move a stubborn deposit?Yes - I'd more likely think that you're looking at a mineral deposit, not etching or corrosion...
Cheers!
Nope...Does this change anyone’s opinion on what the buildup/discoloration might be?
That's why I suggested to look at it with a magnifying glass. If they're pits it was something corrosive to that stainless alloy, and ate some of the surface away. If they're mineral deposits, keep scrubbing with BKF and a fine grit (Scotch-type) fiber pad.Yes - I'd more likely think that you're looking at a mineral deposit, not etching or corrosion...
