How long should a cleaning chemical stand in the line for effective cleaning?

For effective cleaning, a cleaning chemical should generally stand in the line for 15 minutes. This duration allows sufficient time for the chemical to break down any buildup, residue, or biofilm that may be present in the lines. Cleaning solutions typically require this amount of time to ensure that their active ingredients can work effectively on the surfaces they are meant to cleanse, promoting a thorough sanitization process.

Using the correct amount of time is crucial for achieving the desired level of cleanliness and reducing the risk of contamination in any brewing or beverage serving equipment. If cleaning solutions are not left in contact for the appropriate duration, there is a greater chance that the cleaning will be ineffective, potentially leading to problems like flavor contamination, off-flavors in beverages, or issues with hygiene.

While other timeframes might seem reasonable, they either are too short to provide effective cleaning or too long, which may not offer additional benefits and could lead to potential issues with the cleaning solutions themselves or the equipment being cleaned. Therefore, the choice of 15 minutes strikes a balance between effectiveness and practicality for regular cleaning procedures.
