How often should FOB detectors be cleaned to ensure proper functioning?

Cleaning FOB (Foam on Beer) detectors every two weeks is optimal for ensuring they function correctly. These detectors are crucial in maintaining beer quality, as they monitor the presence of foam in dispensing systems. If they are not kept clean, they can become clogged or give inaccurate readings, leading to issues such as excessive foam production or poor beer quality.

The bi-weekly cleaning schedule helps to prevent bacteria and yeast build-up, which can affect both the taste and the appearance of the beer. This frequency strikes a balance between maintaining cleanliness and practicality for most establishments, ensuring that the detectors remain sensitive and accurate without requiring overly frequent maintenance that may disrupt service.

In contrast, cleaning them once a month may allow for too much accumulation of residues, while cleaning them once a week could be unnecessarily frequent for many systems in moderate use, leading to potential over-maintenance without substantial benefit. Therefore, cleaning FOB detectors every two weeks is deemed the most effective approach.
