Auto Keg Cleaner

The joy of kegging is a big step in a homebrewers life.  But once you have the kegs you relize that you still have to clean the kegs to keep the beer tasting great.  With some cheap suplies from Lowes you can accomplish this with ease.

Here is the parts list:
  • A cheap aquarium pump about $16.00
  • Corny keg liquid "Out" about $5.00
  • Corny keg gas "In" about $5.00
  • Clear plastic tubing that will fit on your "pop-its"  .50 a foot at Lowes
  • One T valve about $3.00



The pictures should give you a clear idea of how it goes together.  But you size the "pop-it's" so that they fit on the keg and cut the top part of the "T".  Then attach the T splitter.  From that point size it down to the bottom of the keg and attach the pump.  (I had to heat up the tubing so that it would fit on the attachment.)  And you are ready to go.

Once the cleaner is assembled, you are ready to clean.

  • Plug the drain in your sink
  • Fill the keg 1/2 way with the cleaner of your choice.
  • Fill the sink with the keg inside of it with the same cleaner.
  • Plug the out and in on the keg
  • Put the pump inside the sink and turn on.
The pump will fill the keg and let it overflow into the sink.  This will create a recirculatory effect.

Here are some "Action" Shots:





And your done.  A easy keg cleaner that will go and go.  I normally use this way of cleaning for 3 refills before I take the keg apart for a full cleaning.

Enjoy

  2. I love mine. That thing brings out the lazy in me in a way that I can't even begin to describe. I've left it going for hours and forgotten it.

  3. Excellent. I'll be making something similar and will also use it to clean keg lines and double as an aerator!

    Thanks for the inspiration!

  4. Nevermind, apparently it's a bad idea to run these water pumps dry. So I'll just use it to clean kegs and line. Where did you buy yours?

  5. I got mine from Lowes. It is really a water fountain pump. In the garden area.

  6. I like this idea, however I prefer to clean my kegs with hotter water like 130* F or so. These pond pumps can't be run north of the 80-90 degree mark I beleive. Do you find that to be true with this application? I have a pond pump I currently use for an ice water bath and my immersion chiller which I would work for this.

    1. Brett, I made this cleaner in 2009 and the little pump is still going strong. I do expect some sort of "degrading effect" due to the cleaners. But for the cost of under 20 bucks for the pump it wouldn't bother me to replace it every 2 years or so.

  7. I've got same equipment but implement it a little different.. I have a bucket full of hot water and my cleaning product. I have a pond pump in the bucket with about 60cm of copper tube out the top of the pump, I tap the end together to give it a small opening for some water to come out and then drill a number of small holes around the top of the copper tube. At the join of the copper and pump I have a tee that goes off to a post I connect to the beer out on the keg. I then turn the keg over over the copper (helps if you have something in the bucket to hold the keg off the top of the copper so it doesn't scratch your keg insides. Once thats setup I just turn it on and it recirulates. My next mod will be to add a "RIMS" type of tube to keep the water at a set temprature.

    1. I should add, I've done this to use minimal water usage.

    2. Sounds great anything that reduces water usage is a good thing.
