BLC Beer Line Cleaning Solution - 4oz

In stock and ready to ship.

Use this BLC potassium hydroxide beer keg line cleaner to maintain the quality of your draft beer system over time. The 4-oz size makes it just right for cleaning your home kegerator system.


    Ensure that your kegerator keeps pouring perfect pints by using this specialized BLC Beer Line Cleaning Solution. Its small 4-oz size allows you to use it 8 times, perfect for the kegerator owner or cleaning any short run draft beer system. If you own a commercial draft beer system or find yourself cleaning your beer lines often, you may want to purchase the 32-oz bottle.

    This potent potassium hydroxide solution is carefully formulated to offer maximum cleaning performance for short run draft lines, tap boxes, and kegerators. Draft beer lines should be cleaned out every time you switch out your keg, or approximately every 2-3 weeks.

    Simply add 1/2 ounce of solution to each quart of water, push it through your lines (recirculating for up to 15 minutes), and then flush them with clean water. You can also use this solution to clean your faucet and other draft beer equipment parts in a soaking solution.

    Dirty lines lead to buildup and off-tasting or foamy beer. Get your system clean (and keep it that way) with BLC Beer Line Cleaner.
