Never use a wire brush on stainless.

Good advice, excepting that it should be a non-ferrous or stainless steel brush. Bronze, nylon, stainless steel are OK. You also have to be careful when working with stainless and you contaminate the metal with plain iron.

On another note, all stainless steel can rust if its exposed to the wrong environment. In the brewery, the most hazardous environment typically arises from high chlorides. Using bleach or hydrochloric acid on those metals can be detrimental. The grade of the stainless steel also has a large effect on its corrosion resistance. The cheap stainless that is often magnetic, is more prone to corrosion. The 300 series steel is typically more corrosion resistant. I have to deal with this issue in wastewater treatment. 304 stainless is sort of the bottom line and I have to move up to 316 steel when the corrosion conditions are more severe. I did some work for the South Florida Water Management District years ago and had to spec an even higher stainless grade (317) because it was exposed to seawater. From my experience, brewery use most typically needs only 304 stainless. Just be aware that you can screw that up if you expose it to too much chloride during some sort of cleaning operation.

I was told the same thing by my keg supplier "all SS can rust". I've had an ongoing issue with small rust showing up on the welds of the keg lid handle. Maybe this technically isn't SS that's rusting but the weld.

Once I got the post on (prior to attaching tubing), it started to squirt some of the trub out even after I continued to bleed CO2.

 Are you sure the PRV was locked open?

No, I forgot you can lock it. Next time  ;D

I typically gravity feed my beer into the keg through the open lid via silicone tubing from the fermenter.

This time I tried to do the same thing, but instead of letting the beer flow through the lid, I was going to try and let if low through the "Out" post on the keg (assuming this was a closed transfer).

I assumed I needed to bleed off pressure or else the beer wouldn't be able to gravity flow into the keg. Once I got the post on (prior to attaching tubing), it started to squirt some of the trub out even after I continued to bleed CO2.

After spraying this trub various times, I said &%$& it and transferred like I normally do.

:o I think you need to clean the keg...

Whoops, guess I should've specified...this is the same keg that I'm using to just dump a new batch of beer into an existing empty keg without cleaning. "Lazy Kegging" post...

Could be wort, think I'll try a vinyl brush or just RDWAHAHB

Just to clarify, I ran a silicone tube from my fermenter into the out post of the keg as others mentioned above. Prior to hooking up the tube, I noticed that there was dark green sediment that would periodically spray out of the keg. This is after bleeding off all pressure, perhaps there was more in there as the lid wasn't opened yet.

Yeast and Fermentation / Re: Yeast shipped warm.

FWIW, I tend to order yeast from More Beer and always order 2 ice packs. They are always melted and warm from the two day transit. I just figure it kept it cold longer than without. I think I'll stick to dry yeast during the summer months for now.

I noticed that the below part (Blichmann 1/2" QuickConnector) has, what I believe, is some rust on it. I've tried some hot PBW soaks to no avail. I think the issue is the small groves which I can't get to just using a cloth or paper towel.

Is a wire brush ever appropriate for getting rid of rust or grime on SS? Perhaps I should try a vinyl brush first.

How would you attach the auto-siphon to the liquid post? What if I don't use an auto-siphon anymore and simply fill the keg with a silicone tube from my ball valve on the fermenter.

The tubing from the autosiphon runs to a disconnect which is attached to the liquid post.

You would attach the tubing from your ball valve in the same fashion.

Don't over-think this.  The goes-out from the fermenter attaches to the goes-out on the keg (which is now effectively the goes-in).

Gave this a try yesterday and even after purging the empty keg with the PRV multiple times, gunk kept squirting out of the keg randomly. Did I do something wrong? Figured something was off so I never bothered trying to transfer beer this way.

I'm guessing you can't do a closed transfer without using two kegs. In my case I'm using a keg and a fermenter.

Has anyone ever kegged straight into an empty keg without first cleaning and sanitizing it? I am a stickler for cleaning and sanitation, but the heat has me feeling me lazy lately.

I figured outside of flavors from the last beer, I didn't think there would be any sanitation issues. Cheers and Happy 4th!

Amazing how much one can function on an hour sleep.

My SOP is to pressurize the keg to 20 psig (30 psia) and push the sanitizer out to get the dip tube, beer line, and faucet sanitized, then blow down using the PRV and repeat the pressurize/blowdown process twice more. That *should* reduce the O2 from 21% to <1%. Attach the auto-siphon to the liquid post, open the PRV to start the flow, finish racking the beer, and then pressurize/blowdown three more times to purge the headspace. Once you actually play around with a DO meter, it's shocking how much purging is necessary.

CTSP (chlorinated trisodium phosphate)

5 Star's CMC, in case anyone was wondering. Awesome stuff.

With regards to the ants...pick up some of the Terro brand liquid baits. Non-toxic, works like a charm, and fun to watch lines of ants drinking their last meal.
