On Monday I took the day off to help my wife around the house, and I cleaned 8 kegs. 3 of them were brand-new-to-me kegs (old 3-galllon pin locks) that still had coke in the bottom of them. The rest were kegs that had beer/yeast sludge in the bottom of them. Here's what I did to each keg:
- Released CO2 pressure
- Removed lid, sprayed/scrubbed off any sticky/dirty stuff
- Sprayed out inside with hot water from kitchen sink sprayer
- Removed posts, took old "Coke" plastic wrap off the "new" kegs, stabbed my fingers in the process
- Scrubbed out posts, inspected poppets
- Used dip tube brush on gas/liquid tubes
- Replaced o-rings that looked to be in bad shape
- Lubed said o-rings
Once I had done this for all the kegs, which took approximately 5 minutes / keg, I did the following:
- Put hot PBW in, sealed lid, hit with C02
- Shook up PBW, sprayed it out of gas post
- Pushed PBW to next keg with C02
- Removed lid, rinsed lid and keg with hot water
I did these steps while spreading mulch - I'd spread 2 bags of mulch, go back inside and set up the next keg. I've also done this in the past while watching TV, doing dishes, etc.
For the last keg I just took the QD off one end of my jumper and pushed the pbw into my drain.
Then I put starsan in one keg, shook it up, and pushed it to the next keg, and so on till they were all sanitized. At the end I had a nice keg full of starsan which I used to clean my picnic taps.
So compared to bottling, this is a gigantic timesaver, and doing this to 8 kegs is much more managable than cleaning and storing 16 cases of bottles! Even if they're already de-labeled, dealing with bottles is a huge time suck.
The only downside I see? My kids used to help me bottle, now they've started bugging me about when we'll bottle again, since they had so much fun.
