cleaning and passifying question
« on: August 28, 2013, 08:28:38 AM »
My new conical came with first time cleaning instructions. They say to clean inside and out with a grease cutting soap. Would dish soap work for that? I don't think oxyclean cuts grease. Then it says to use Bar Keepers Friend as my cleaner. This has Oxalic Acid which passifies my kettle. Again would oxyclean or PBW passify my Conical?

AFAIK, neither Oxi or PBW will passivate.  I've always heard that BKF will, but there's been some debate about it.

According to Palmer, Barkeepers Friend does a deep cleaning. O2 from air passifies almost instantly.

Is it really necessary to passify stainless steel?

I was hoping to fill it this weekend. I guess that won't be happening  :( It appears to take a week to passify.

Where do you get the one week time frame?  That doesn't sound correct to me, though I am not an expert.

I was under the impression that it passivates pretty quickly, as Jeff states above.

I read it on one of the sites I googled. Stout tanks just called me and told me it would be OK to use the thing 1 time before passifying it. But I just ran out and bought some bar keepers friend. If it passifies quickly I may go ahead and use that stuff now just to be on the safe side. I will disassemble my ball valves and passify those after my first use.

After I posted I saw on Stout Tanks website that they say to wait a week.

I'd go with whatever they tell you rather than trust me.  I've made the mistake of trusting me before.

I just went over it with barkeepers friend. They returned my call and told me I could use it one time before I passify it. So I will just clean it with barkeepers friend again after my first use.

Along with being a really nice guy, John is a Metallurgical Engineer, so he might now something about it.

So the BKF is that oxalic acid based cleaner you use to get the SS to passivate itself....

That was really helpful. I just cleaned with BKF but used paper towels rather than scouring pads. After my first use I will do it again but use the pads this time.

That's the info I read when I was looking at some kegs with rust on the inside. Couldn't find it earlier today.  Thanks for the link.

A blue or green scrubbie is recommended by most.
