How best to store sanitized Corny kegs for future use?

I use Cornys for secondary fermenters and serving. I use a homemade carboy/keg washer to clean the keg with HOT water, then sanitize with Iodophor in COLD water. The washer has extra "arms" that attach to the keg posts via ball-locks, so the dip tubes inside the keg are thoroughly cleaned/sanitized as well as the keg body.

I drain the Iodophor out of the washer into a bucket, and then drop the lids/o-rings/relief valves in the bucket. After draining, I reassemble and store until next time.

I don't really want to sanitize it again before use. Should I:

1) Leave a few cups of iodophor in the keg ?

2) Pressurize the keg with CO2 ?

3) Both ?

4) Skip the above, don't be lazy, just sanitize again before next use ?

What do you do / think ?

P.S. The carboy/keg cleaner wasn't my idea, I saw on it on homebrewtalk or somewhere like that. What was my idea was to tap a hot water line in my garage, adding a tee, ball valve, and garden hose QuickDisconnect. HOT water makes cleaning the mash tun, boil kettle, and everything else sooo much easier.

I only used kegs for serving. When one blows I just put it aside as itís full of CO2 and nothing will happen. I only clean it a day or two before refilling by soaking in Oxiclean (one scoop and fill with hot water and let soak for 1-2 days and then rinse and sanitize right before filling).

I clean but do not sanitize my kegs until I am ready to fill them. I keep the parts in a ziplock, put the long dip tube inside the keg via the lid opening and cover the mouth of keg with a paper towel and put the parts bag on the paper towel.

I use the relatively new Ss keg cleaner and love it. I have enough kegs that a keg cleaning day usually doing 6-8 kegs. The Ss cleaner is a CIP like pump that attaches directly to a keg. Once a keg is attached you move it from the cleaner to a rinse and then to a sanitizer (non foaming -- I use saniclean).

Each is done in a separate bucket and the keg is moved through each stage.

I rinse a dirt keg with a powerful spray hose and dump. I attach the Ss cleaner and do stage 1 cleaning for 20-30 minutes (using 45g of PBW in 2 gallons). I then rinse for 10 minutes, then do stage 3 sanitizing for about the same amount of time. The corny lid follows the keg through the three stages.

When this is all done I fill the keg with CO2 and attach a ball lock connector to the liquid out post a few times to get as much sanitizer out as posible. A tiny bit remains but it seems to have no effect on the beer. I then store the kegs, sometimes for many months, in this state before filling them. I do no more sanitizing or anything beyond opening the lid (after purging the CO2) and transfer the product in.

I do use a bucket heater on a temperature controller to keep the cleaner (stage 1) or rinse water (stage 2) at 140F. While I am cleaning I am heating the rinse water, and while I am rinsing I am heating the next stage 1 cleaner.

Works like a champ with zero issues thus far. I love the Ss keg washer.

What sanitizer do you use? Some (like StarSan) are no-rinse so no concerns at all if some stays behind.

i'm a big fan of sanitizing equipment right before use. kegs, starter flasks, conical, you name it. i don't want to worry about potential contamination issues with equipment sitting around for days, weeks or even months after being sanitized. i definitely clean everything before storing but a simple water rinse is the last step i take before storage.

I clean my kegs as time permits, when several of them stack up for cleaning, and I get the motivation to do so. Basically I'll throw about an ounce of oxyclean in and fill about 1/4 to 1/3 full with water, shake the crap out of it and let it sit anywhere from a day to 2 weeks (motivation thing). Then I'll do a thorough rinse, fill one to the brim with sanitizer (star-san), cover, and sequentially use CO2 pressure to push out the sanitizer to the next clean keg...and repeat. Once sanitizer get's pushed out completely, there is only CO2 under a small amount of pressure in the keg. The kegs will stay that way until the next beer is ready for kegging (sometimes months away, but never had any issues). When kegging time comes, there is always a little pressure in the keg to confirm that seals are good to go....if not, then I clean/sanitize that particular keg immediatly and check all seals.

I used to clean the kegs as soon as they blew but now I tend to just pull the kegs from the fridge when they blow and store them until I need to use it again. Once I need an empty keg I just clean, sanitize and use it.

Older thread but this is what I do as well.

Reason being that if you clean/sanitize and then store it full of atmosphere, you're just going to have to re-sanitize it again right before you fill it. So why the extra work? Leave it full of CO2 until you're ready to use it and clean/sanitize it right before. Less work that way. You could fill with CO2 after sanitizing and then store I suppose as the odds of something growing is much lower to next to impossible. Cleaning/sanitizing right before use is definitely the least amount of work and the risk is the lowest, so that's what I do. I don't find kegs are harder to clean when they've been sitting sealed with CO2 after use for 6+ months as compared to cleaning them immediately. The stuff doesn't dry out as there's no way for that to happen.
