Minimum Recommendations for Effective Draught Beer Line Cleaning
Clean beer lines every 14 days (2 weeks). Clearly posted documentation of line cleaning and servicing records is recommended in all keg coolers.
• Turn off your glycol system if possible, and push beer from lines with cold water.
• Clean lines with caustic solution at 2% or greater concentration for routine cleaning of well maintained lines, or at 3% for older
or more problematic lines. Contact your chemical manufacturer to determine how much chemical is needed to achieve these recommended concentrations. If you use non-caustic based cleaners such as acid based or silicate based cleaners, be sure to use the cleaning concentrations recommended by the manufacturer. For best results, maintain a solution temperature of 80o – 110oF during the cleaning process.
• Using an electric pump, caustic solution should be circulated through the lines at a minimum of 15 minutes at a flow rate of up to 2 gallons per minute. If a static or pressure pot is used (though not recommended) the solution needs to be left standing in the lines for no less than 20 minutes before purging with clean water.
• Disassemble, service and hand clean faucets; hand clean couplers. Clean and inspect any FOBs and beer pumps; disassemble and hand clean as needed.
• After cleaning flush lines with cold water until pH matches that of tap water and no visible debris is being carried from the lines.
• *Every 3 months (Quarterly), after normal caustic line cleaning, clean lines with acid, using the cleaning Brewers Association ￼￼￼￼￼￼￼￼￼￼￼￼￼￼￼concentrations recommended by the chemical manufacturer.
