5 Things to Look for When Choosing a Draft Line Cleaning Company
Clean draft lines are essential to serving fresh, consistent draft beer. But professional draft line cleaning should involve more than simply running cleaning solution through a beer line.
A quality draft line cleaning company should help protect the entire draft system. That means following a consistent cleaning program, using proper procedures, cleaning the components that come into contact with the product, documenting system conditions, and recognizing problems before they become larger service issues.
For bars, restaurants, breweries, and other operators comparing draft line cleaning services, here are five important things to look for.
A Consistent and Appropriate Cleaning Schedule
Draft beer lines need to be cleaned on a regular schedule—not just when the beer starts tasting off or the system develops a problem.
Beer residue and organic buildup accumulate inside draft lines and components over time. By the time an operator notices an obvious change in flavor, aroma, or pour quality, the system may already be overdue for attention.
A professional draft line cleaning company should establish a consistent cleaning schedule and reliably maintain it. The appropriate cleaning program may depend on the system, products being poured, operating conditions, and applicable industry recommendations.
Consistency is important. Cleaning should be preventative maintenance, not a reaction to a problem.
When evaluating a beer line cleaning service, ask how cleaning schedules are managed and how the company ensures visits aren't missed.
Proper Cleaning Procedures and Chemicals
Effective beer line cleaning requires more than putting chemical into a line and rinsing it out.
The cleaning chemical, concentration, temperature, contact time, and cleaning method all affect how well deposits and buildup are removed from a draft system.
A professional draft beer line cleaning company should use chemicals specifically intended for commercial draft systems and follow established procedures for their use.
A proper cleaning process should account for:
Correct chemical concentration
Adequate cleaning and contact time
Thorough rinsing after cleaning
Appropriate procedures for routine and periodic deeper cleaning
The condition and configuration of the individual draft system
Improper cleaning, such as using household detergents or insufficient contact time, can leave behind residues that affect beer flavor and safety. A knowledgeable company will follow established protocols and adjust procedures as needed.
Cleaning Beyond Just the Beer Lines
One of the easiest ways to distinguish a thorough draft line cleaning service from a basic one is to look at what happens beyond the line itself.
Beer touches more than tubing.
Faucets, couplers, FOBs (foam-on-beer detectors), jumpers, and other components throughout a commercial draft system can all accumulate buildup or develop problems.
Faucets in particular should receive proper attention. Components that can be appropriately disassembled and cleaned shouldn't be ignored simply because cleaning solution has been circulated through the system.
FOBs and jumpers should also be inspected. These areas can provide valuable clues about the cleanliness and overall condition of the draft system.
A good question to ask a potential cleaning company is simple:
What exactly gets cleaned and inspected during a normal visit?
The answer should involve more than just the beer lines.
Documentation and System Monitoring
A quality draft line cleaning visit should also serve as a routine health check for the draft system.
Technicians are already working directly with the equipment, which puts them in a good position to spot developing problems before they affect beverage quality or turn into larger service issues.
Depending on the system, technicians may be able to identify concerns such as:
Abnormal beer or walk-in temperatures
Glycol system performance issues
Dirty or damaged FOBs
Worn or aging jumpers
Gas leaks or pressure concerns
Damaged faucets or couplers
Equipment that may need repair or replacement
Service records are equally important.
Cleaning dates, system observations, problems found, and recommended repairs should be documented so operators can track the condition of their draft system over time.
This becomes particularly valuable when the same issue appears repeatedly. Instead of treating every service call as an isolated event, good documentation can help identify patterns.
When evaluating a draft line cleaning company, ask what is inspected during each visit and what documentation is provided afterward.
A cleaning company should be able to tell you more than simply, “The lines were cleaned.”
Experience with Commercial Draft Systems
A draft cleaning technician doesn't necessarily need to rebuild an entire draft system during every cleaning visit. But they should understand how one works.
Commercial draft systems depend on several factors working together, including temperature, gas pressure, restriction, refrigeration, glycol circulation, regulators, FOBs, couplers, faucets, and the draft lines themselves.
When one of those variables is wrong, the symptoms can sometimes look like a cleaning problem.
Foaming is a good example. Dirty equipment can contribute to poor pours, but so can temperature problems, incorrect pressure, damaged components, refrigeration issues, or an improperly balanced system.
A technician who understands commercial draft systems is better equipped to recognize the difference.
That knowledge also makes routine cleaning visits more valuable. Instead of simply completing a cleaning procedure and leaving, an experienced technician can flag something that doesn't look right and recommend further investigation when necessary.
Red Flags to Watch For When Choosing a Draft Line Cleaning Company
Not all draft line cleaning services deliver the same quality. Watch for these warning signs:
Inconsistent scheduling: Companies that don’t offer or enforce regular cleaning intervals may leave your system vulnerable.
Extremely quick cleanings: Rushing through the process often means corners are cut, reducing cleaning effectiveness.
Failure to disassemble and clean faucets: Skipping faucet and coupler cleaning misses critical contamination points.
Lack of documentation: No service records or reports make it hard to track system health or recurring issues.
Technicians unable to explain findings: If the technician cannot describe what they found or recommend solutions, they may lack expertise.
Avoid companies showing these signs to protect your draft beer system and beverage quality.
Practical Checklist for Choosing a Draft Line Cleaning Company
Use this checklist when comparing professional draft beer line cleaning services:
How often will the draft system be cleaned?
How are recurring cleaning visits scheduled and tracked?
What cleaning chemicals and procedures are used?
Are faucets and other product-contact components cleaned?
Are FOBs, jumpers, couplers, and other equipment inspected?
Are system conditions documented during service?
Will technicians flag potential equipment or performance problems?
Do the technicians understand commercial draft systems beyond line cleaning?
Will you receive a record of the work performed?
The answers can tell you a lot about the level of service you're actually purchasing.
Draft Line Cleaning Should Be Preventative Maintenance
Professional draft beer line cleaning shouldn't simply check a box.
A good cleaning program protects beverage quality while creating regular opportunities to inspect the equipment responsible for getting that beverage from the keg to the glass.
For operators, that means looking beyond price alone when choosing a draft line cleaning company. Consider the cleaning procedure, consistency, technician knowledge, documentation, and what is actually being inspected during each visit.
