New SS Tun?Kettle question

[Sturg78]

Hello,

I have recently upped my game to full stainless with a new kettle. I have been using aluminum to this point and heard all of the wondrous things about how SS is inert and hard to mess up using. I opened my new kettle, rinsed it out thoroughly with water, and then went about my mash. It wasn't until the end of my mash I noticed rainbow circles at the bottom of the pot where the pot had dried. I realized in my haste to use my new toy I may have skipped a few prepping steps and so I ask you folk:

-Am I in danger of killing friends because I didn't passivate the kettle? Will I notice it taste wise in the beer?

-Now that the kettle is empty, what should I do to clean and prep it for the next brew? I am using the pot as both a kettle and a mash tun if that changes anything.

-I have a welded ball lock spigot installed, is there any maintenance I should be performing to keep the innards clean?

As always, thanks bunches for the help

cheers

No one will die.

Clean the kettle with Bar Keeper's Friend. Available at walmart and most other stores next to comet cleaner.

Ball valves will hold sugar around the ball if you open them fully when cleaning. Open them a 1/4 turn and rinse with cleaner and rinse water to flush out the sugars and cleaning solution.

Rinse with hot water and clean between brews.
