A kegerator is a refrigerator that stores and cools kegs of beer. A tap is connected to the top to dispense the beer. The kegerator can keep draft or home-brew beer fresh for a couple of months. Keeping your kegerator clean is important since it will ensure the quality of your beer and make sure there is no contamination in future kegs. To clean your kegerator, clean it between each keg, soak the faucet and keg coupling, and flush the beer lines.

Maintaining the Exterior

1
Clean your kegerator after each keg. Every time you use your kegerator, you should clean it afterwards. This helps remove all beer residue from the line and faucet. Cleaning after every use helps you avoid messing up other beers.^{[1]

Turn off the kegerator. Before you start cleaning, shut down the kegerator completely. Unplug the kegerator. Make sure you turn off the CO2. Then, you want to close the regulator, disengage the tap, and completely remove the keg.^{[2]

Wipe down the surfaces with mild soap and warm water. Start by cleaning the outside of the kegerator. Make sure to wipe down the tap, lines, spill tray, regulator, and tank. You also should wipe the inside of the cooling unit. Then, clean the inside surfaces, such as the beer lines, the spigot, and the tap. Use soap without any scent and warm water to wipe down all surfaces.^{[3]

- Some people make their own cleaning pumps with quart bottles or soda kegs and tubes.
2
Disassemble the faucet and remove the keg coupler. To start sanitizing your kegerator, you need to remove the faucet and keg coupler. Use your faucet wrench that came with your kegerator to loosen the faucet, and rotate it to the right to loosen it. When it is loose, twist it off with your hands.^{[5]

- The solution will run through the beer lines and empty into the bucket.
- Rinse the beer lines at least three times. You want to make sure to remove all cleaning solution from the beer lines.
4
Check the parts. Before reassembling your kegerator, check the various parts to make sure they are okay. Check the rubber gasket and the O-rings. These wear fast, so if they show wear or have become flattened, replace them.^{[12]

- Make sure there is still enough food-grade lubricant on the O-rings.
- Also check the washers to make sure they are still in good shape.
5
Reassemble your kegerator. Put the faucet back together and reconnect it to your kegerator by turning the coupling nut counter-clockwise. Make sure the sealing gasket is back in place. Connect the keg coupler to the beer line and CO2 hose.^{[13]
