    Clean Beer Lines AND Dispense Quality Beer

    Foamy draft beer can be caused by the build-up of bacteria, yeast, mold, and beer stones within a beer line. Un-clean beer lines lower the quality and taste of beer. It is important to clean beer lines, faucets regularly, and keg couplers to ensure the dispense of high-quality beer.

    Micro Matic's beer line cleaning kits help maintain the sanitary level of your equipment and ensure the dispense of fresh-tasting quality beer.

    The simple cleaning process takes only a few minutes and is easily accomplished by using either a hand-pumped cleaning bottle or a pressurized cleaning bottle. This process involves pumping water mixed with cleaning chemicals into the beer line and letting it soak for the time prescribed by the chemical manufacturer. Then thoroughly flush the beer line with water to remove all traces of the cleaning chemical.

    The last and most often overlooked step is to soak the keg coupler and faucet in water with cleaning chemicals, brush them clean with a cleaning brush and rinse them clean with water.

    Cleaning Kit Use Instructions

    Regular cleaning of the faucet, beer line, and keg coupler is critical. If this is not performed, the beer will foam. Additionally, bacteria, yeast, mold, and beer stone will build up and quickly degrade the quality of draft beer. Routine cleaning is essential to maintain quality and fresh taste.

    Routine Maintenance and Inspection

    Keg Coupler - After cleaning, it is an excellent opportunity to check the probe o-rings (102-526), and the bottom seal (102-521) on the keg coupler is in good condition. Verify the probe o-rings on the keg coupler are properly lubricated with a food-grade lubricant (FT101L) to allow the coupler probe to move freely; this prevents wear and tear when the keg coupler is tapped and untapped on the keg.

    Faucet - Check the friction washer (4308), coupling washer (4318), and shaft seat (4324) on the faucet are in good condition.

    To better understand these parts, see a typical keg coupler diagram and faucet diagram (pictured below).


    For residential applications: Cleaning should be performed after every keg or at a minimum of every two weeks. Routine cleaning is essential to maintain quality and fresh taste.

    For commercial applications: Cleaning should be performed at least every two weeks or following brewery recommendations and/or state guidelines.

    Only use cleaning chemicals specifically manufactured for beer line cleaning. Only chemicals specifically manufactured for beer line cleaning will dissolve the buildups of bacteria, yeast, mold, and beer stone that occur with draft beer. And for safety, all directions on these cleaning chemicals must be followed completely.
