Disassemble, Cleaning and Sanitizing a Cornelius Style Keg

    So, here we have a dirty empty keg and a beer. Two things need to be done here. Clean and sanitize the keg and drink that beer

    I start by removing the lid from the cornie. I have already released the pressure via the relief valve

    We will need tools to remove the ball valves, poppets, dip tube and air inlet. I use an 11/16 socket for the smaller ones, a 7/8 socket for the larger ones. The star shaped one, I just use a set of channel locks

    I need a better picture of this, but you can see the poppet inside the actual assembly of the ball lock.

    In order, we have the inlet tube, the poppet and the ball lock assembly. This is the IN side of the keg

    The OUT side of the keg will have a poppet and assembly. Other than those two pieces, you have the dip tube

    S, besides the keg shell, here are all of the parts. We can see the lid, the dip tube and you'll notice that for ease, I separate the IN and OUT sides of the kegs ball lock assemblies

    Here is the technique I use to knock the loose yeast from the keg, and also my wife's finger over the left side of the lens

    I rotate and dump and continue to rinse until it is nice and clean

    Now it is time cor a cleaning agent. I use Oxy Clean. It works well. You can use PBW or whatever your choice is for cleaners. Oxy is cheap, plentiful and works great.

    I usually add 1.5 quarts of hot hot water and this amount of Oxy

    I use my sausages to cover the inlet and outlet ports and shake it violently

    The dip tube goes into the tub with about 1/4 inch of water. I add the same amount of Oxy as I did for the keg, maybe a bit more if your tub doesn't slant like mine.

    I pour a little Oxy on the ball lock assemblies

    With the dip tube and the ball assemblies soaking, I take a bit of time and use my carboy brush on the inside of the keg.

    Now I turn the top of the keg to inside the sink and rinse first with hot water. I am actually spinning the keg so I get every square inch rinsed. I then switch to cold water and rinse again.

    Now we are going to need a sanitizer. I use Star San and prefer it as a sanitizer. I have tried ever other method and have found that star san is the best.

    I use about this much star san to a quart of water. You don't need to mix up a whole bunch of this as it just needs two minutes of "wet time" to sanitize. The foam is your friend

    This is what it looks like prior to shaking it up with the lid on

    And after a good shaking. The foam creates the wet time that is necessary for sanitizing.

    I figured I needed to replace the sanitizer in the racking cane and after rinsing the dip tube I hook it up to the racking cane and use the end of the tube to pour sanitizer on the ball lock assemblies.

    I put the poppets in the respective assembly and put the dip tube and inlet tube in their holes and quickly flip the ball lock assembly onto the threads and tighten them down. I do my best not to overtighten and use a slapping technique with the socket wrench as to not torque it on there
