What is the recommended temperature for the line cleaning solution?

• A. 50-70F
• B. 80-110F
• C. 100-130F
• D. 40-60F

Answer: (B)

The recommended temperature for the line cleaning solution is typically in the range of 80-110°F. This temperature range is effective because it helps to dissolve residues and organic materials that accumulate in draft beer lines. Warmer solutions can enhance the cleaning process by allowing surfactants in the cleaning solution to work more effectively, thereby breaking down proteins, sugars, and other compounds that contribute to off-flavors and blockages.

Additionally, using a solution that is too cold may not efficiently remove buildup, while extremely high temperatures can risk damaging the lining of some beer lines or fittings. Therefore, the 80-110°F range strikes a balance that maximizes cleaning efficacy while maintaining the integrity of the draft system components.
