Draft Beer 101: The Basics of Beer Line Cleaning

cleaning kit

If you are among the lucky souls with your very own kegerator, please, for the love of all that is good and holy in this world, clean your lines. It’s really not an optional thing.

If you don’t clean your lines after every keg, you’re allowing sediment, bacteria, and mold to build up and taint the flavor of your new, fresh keg. And that’s pretty gross. Not to mention, a waste of money.

Beer Line Cleaning Kit in Action

For home use, we suggest beer line cleaning kits that use air pressure (either hand-pumped or powered by your CO2 tank) to push a cleaning solution through your lines. Doing this is simple, quick, and it wipes out all the gunk that harms the taste of your beer and can cause excess foaming. When working on your lines, we also suggest cleaning your faucet and coupler. This will save time and keep all your parts on the same schedule. You can clean these components and kill any mold buildup with a simple faucet brush

We have a variety of kits on our website,  step-by-step instructions on how to properly use the kits, and this old but incredibly useful video to guide you through the process:


While you’re at it, keep your glassware clean, too. Every part of the draft beer dispensing process is imperative to quality taste, and dirty (i.e., not “beer clean“) glassware is an all-too-common mistake in home and commercial bars alike.

Clean and Dirty Beer Glasses

The bubbles on the right glass are a result of dust, dirt, and soap residue.

Think of it this way: if you were dining at a restaurant, and you saw your fork had some crusted food on it from a previous customer, would you use it? Probably not. Drink residue, or worse, detergent residue on a glass will affect the visual presentation and the taste of your beer, much like food residue on an eating utensil. So when you’re cleaning your drinking vessels, do not use dish soap. Use a glassware cleaner, rinse with hot water, and drip-dry completely before use.

Follow these tips at home or at your bar, and we guarantee you’ll be serving the freshest, most flavorful beer possible. If you have any further questions about the cleaning and upkeep of your draft beer system, feel free to contact us by phone at 877.636.3673, by email at sales@kegworks.com, or through any of our social media networks. Cheers to good, clean beer.

    I didn’t think that a perfect pint of beer is actually more technical than I thought. I guess like all things that are awesome, it takes work, proper handling, and upkeep. I would say the most important factor for me would be to keep it clean.
