To clean your Cornelius kegs, there are a few different options available. One common cleaning agent that is widely used is a sanitizer. Sanitizers are effective at killing bacteria and preventing contamination in your kegs.
One option for a sanitizer is a bleach solution. You can mix about one tablespoon of bleach with one gallon of water to create a sanitizing solution. However, it is important to thoroughly rinse your keg after using bleach, as any residual bleach can negatively impact the taste of your beer or other beverages.
Another option is to use a commercial sanitizer specifically designed for brewing equipment. These sanitizers are often made with chemicals like iodine or acid-based compounds that are effective at killing bacteria and other microorganisms. These sanitizers typically come in concentrated form and can be diluted according to the manufacturer's instructions.
To clean your keg using a sanitizer, start by ensuring that the keg is completely empty. Remove any remaining liquid or debris from inside the keg. Then, take about one gallon of the sanitizer and pour it into the keg. Make sure to put the cap securely back on the keg.
Next, pressurize the keg to about 10 psi or higher until the cap is sealed. This may require using a higher pressure, such as 30 psi in some cases, to ensure a tight seal. Shake the keg vigorously to ensure that the sanitizer coats the entire inside of the keg. This agitation helps to remove any stubborn residue or bacteria clinging to the keg's surfaces.
After shaking the keg, let it sit for a few minutes to allow the sanitizer to do its job. The contact time recommended by the sanitizer manufacturer is typically stated on the packaging. Once the appropriate contact time has elapsed, carefully release the pressure from the keg and remove the cap.
Now, thoroughly rinse the keg with clean water to remove any remaining sanitizer. Pay close attention to all parts of the keg, including the dip tube, posts, and keg lid. Rinse until you no longer smell or taste any sanitizer residue.
It is important to note that cleaning your kegs regularly is essential to maintaining their cleanliness and preventing off-flavors in your beer. After each use, make sure to rinse the keg thoroughly with hot water to remove any leftover liquid. Sanitizing should be done just before filling the keg with a new batch of beer or other beverage.
Using a sanitizer is an effective way to clean your Cornelius kegs. Whether you choose a bleach solution or a commercial sanitizer, make sure to follow the instructions provided and thoroughly rinse the keg after sanitizing. Keeping your kegs clean and sanitized will help ensure the quality of your homebrewed beer or other beverages.
