Time after scrubbing ?
My stainless steel kettle had some scorch marks that needed a fair amount of BKF and elbow grease to remove. It was certainly nice and shiny by the time I was done with it. That was about 3 days ago.
How long should I wait before considering the kettle safe to use? Is SS activation tougher than I think and I really didn't scrub it all off like I would have if it had been Aluminum?
It's Stainless steele, you can use it immediately. That's one of the beauties of S.S. You can passifate it by using a little vinegar and then air drying it for a day. It's not on an industrial scale, but it does work. Easy clean up is the reason I love stainless steele over aluminum. You can use caustics and acids on S.S. but be carefull with chlorine bleach, it can pit your S.S. and will surely eat aluminum.
I don't go for a glass shine with my SS pots. I shrub them down a few times with Straight A, use my plastic scratch pad to remove chunks, and make sure I get them as clean as possible.
Mine have stains. I just don't care. I don't ferment in them and considering they are boiling on brew day that is going to kill anything bad in them.
Sometimes I clean all my equipment on brew day, other times I wait days. Either way though, once I clean it I never use it the very next day. I always clean again before I brew. But if you just cleaned your pots and need to use them, you don't have to wait at all.
I almost always leave Star San suds behind when I began using my things.
I clean my kettle back to looking new once a year. No reason to do it more than that, clean the gunk, dry, repeat.
Have you tried sodium percarbonate?
