Default Blichmann Kettle Has Rust Spots

I have been using a 10 gallon Blichmann Kettle for my homebrewing for about a year now. I know it is 300-series stainless steel, which should not have rust issues, but my kettle has developed small rust spots at the bottom of the kettle.

The attached pictures show the small rust spots. It IS rust; I scratched some off and tasted it. It IS in the structure of the kettle, not just a surface stain from a small steel particle that settled on the bottom. It seems like the kettle is pitting.

A Blichmann representative rquickly esponded to my inquiry. After ruling out one possible cause, they recommended cleaning off the rust, and monitoring the pot to see if it rusts further in the future. They said if it does, that they will take care of it, rest-assured. Thanks, Blichmann!

If you get some Barkeepers friend and mix up a paste, apply and let sit for 5 or 10 minutes and then scrub, light rinse, it'll bring the rust stain out. For tougher spots, let it sit longer before scrubbing and rinsing.

One other note, don't let oxyclean or pbw sit unmixed on the surface, that's how my first spots like this showed up. But they've all come our with BKF and some elbow grease.

I have two Blichmann kettles I've been using for many years. They're immaculate, inside and out. When I upgrade, they'll be bigger Blichmanns...

Cheers!

Stainless is a bit of a misnomer, certain acids will oxidize it. Barkeeper's Friend is a great and easy fix. Don't leave any cleansers in a kettle too long...

The craftsman that constructed the kettle may have used a consumable that had been contaminated with mild steel. Another possibility is you've contaminated it yourself. Have u used a metal spoon?

I am using a stainless steel spoon. The spoon has no rust.
