Aluminium Kettle Problems

[felipefranco]

Hey, guys

I have some doubts about an aluminium kettle I user to heat sparge watter.
I've used it for a couple of times without having any problem. I just brew with bottled watter.
Last week, I boiled some tap water and the kettle developped a black layer where the water was. It hasn't naver happend with any kettles I have, even with the boil kettle
My tap water is from an artesian aquifer and it was some minerals on it.
Is that ok or should I use any problem to remove this layer?
I'm sending you some pictures of it. You can notive the difference in color from the edge to the rest of the kettle.

Thanks in advance!

Not a problem, that is very normal for an aluminum pot...it is oxidation and nothing to worry about.

In fact you should leave it alone. It protects the alum. pot.

More importantly, imo, the oxide layer protects the beer from the raw aluminum.

So, "Good Thing". And try to leave it intact...

Cheers!

That's what is called "seasoning." Definitely leave alone and RDWHAHB.
