How do you clean an airlock bubbler?

Answered by Joseph Vos

Cleaning an airlock bubbler is an essential task in the process to ensure a clean and sanitary environment for your . There are a few different methods you can use to effectively clean an airlock.

1. Gather the necessary supplies: Before starting the cleaning process, gather the following supplies: brewery cleaner (such as Oxiclean or PBW), hot , a container large enough to hold the airlock, and a brush or pipe cleaner.

2. Prepare the cleaning solution: Fill the container with hot water and add the recommended amount of brewery cleaner. Follow the instructions on the cleaner's packaging for the appropriate dilution ratio. Stir the solution until the cleaner is fully dissolved.

3. Disassemble the airlock: Remove the airlock from the fermentation vessel or bung and disassemble it into its individual components. This usually consists of a plastic or glass chamber and a collection of gaskets and valves.

4. Soak the airlock: Place the disassembled airlock into the container with the cleaning solution. Ensure that all parts are fully submerged. It is best to let the airlock soak overnight, allowing the cleaner to loosen any residue or build-up.

5. Remove stubborn residue: After soaking, inspect the airlock for any remaining residue. Use a brush or pipe cleaner to gently scrub away any stubborn build-up, ensuring that all surfaces are thoroughly cleaned. Pay extra attention to any narrow or hard-to-reach areas.

6. Rinse thoroughly: Once you are satisfied with the cleanliness of the airlock, thoroughly rinse it with clean water to remove any remaining cleaning solution. Ensure that all parts are rinsed and free from any residue.

7. Sanitize: Before reassembling the airlock, it is crucial to sanitize it to eliminate any potential bacteria or contaminants. You can use a sanitizing solution, such as Star San or a diluted bleach solution, to sanitize the airlock. Follow the instructions on the sanitizer's packaging for the appropriate dilution ratio and contact time.

8. Reassemble and store: Once the airlock is sanitized, carefully reassemble it, ensuring all parts fit snugly together. Store the airlock in a clean and dry place until it is needed for future use.

Additional tips:
– If you don't have access to brewery cleaner, you can use bleach as an alternative. However, be cautious when using bleach, as it can leave residues or off-flavors if not rinsed thoroughly.
– Regular cleaning and maintenance of the airlock will prevent build-up and potential contamination. It is recommended to clean the airlock after each use and sanitize it before each use.
– If you encounter persistent residue that is difficult to remove, you can try using a specialized brush designed for cleaning airlocks or a pipe cleaner to reach into narrow areas.
– Personal experiences: As a brewer, I have encountered various levels of build-up and residue in airlock bubblers. Soaking the airlock overnight in a brewery cleaner solution has always been my go-to method. It effectively loosens the residue, making it easier to clean. I have also found that using a brush or pipe cleaner helps remove stubborn residue from the airlock's intricate parts. Sanitizing the airlock before use provides peace of mind, knowing that my beer is fermenting in a clean and safe environment.
