BLC Beverage System Cleaner is a professional-strength, liquid alkaline solution designed to remove protein, yeast, and organic soils from draught beverage lines. This 32 oz bottle is the industry standard for maintaining beer flavor and system hygiene. BLC is formulated to be low-foaming and effective even in hard water, ensuring that every inch of your tubing, shanks, and faucets are thoroughly sanitized. Regular use prevents the buildup of "beer stone" and off-flavors caused by bacteria.
