Draft Beer Line Cleaning Chemicals, Kits & Equipment
Clean lines are the foundation of quality draft beer. Yeast, protein, hop resins, and beer stone build up inside beer lines, faucets, and couplers within days of use — causing off-flavors, excessive foam, and bacterial contamination that no amount of good beer can overcome. The Brewers Association mandates a minimum 14-day cleaning cycle for all commercial draft systems. We stock everything you need to stay on schedule.
Cleaning Chemicals
- Alkaline (caustic) cleaners — the primary cleaning agent, including Veracity™ C-DLC Heavy-Duty Caustic Cleaner; dissolves organic deposits including yeast, protein, and hop resins; use every two weeks as your standard line cleaner
- Acid cleaners — removes beer stone (calcium oxalate) and mineral scale that alkaline cleaners can't touch; use periodically (every 3–6 months) as a supplemental deep clean
- Sanitizers — kills residual bacteria after cleaning; used as the final step before returning lines to service
Cleaning Equipment
- Cleaning cans — hand-pump cans for manual line cleaning; the standard method for direct draw and single-keg systems
- Electric recirculating pumps — continuously circulate cleaner through lines for more thorough cleaning with less labor; recommended for long draw systems and high-volume operations
- Cleaning adaptors & components — faucet plugs, coupler adaptors, and fittings for connecting cleaning equipment to your specific system configuration
Cleaning Kits
- Direct draw cleaning kits — everything needed to clean a direct draw or kegerator system; includes cleaner, can, and adaptors
- Economy cleaning kits — budget-friendly starter kits for operators setting up a basic cleaning program
The Cleaning Process
- Alkaline clean — circulate or push alkaline cleaner through lines; soak 15–20 minutes; flush with water
- Acid clean — follow with acid cleaner periodically to remove beer stone; flush thoroughly
- Sanitize — apply sanitizer as final step; do not rinse after sanitizing
- Brush clean faucets — disassemble and brush-clean faucets every two weeks alongside line cleaning

Beer Line Cleaning FAQ
What's the difference between alkaline and acid line cleaners?
Alkaline (caustic) cleaner is your everyday cleaner — it breaks down yeast, protein, and hop resins and should run through the lines every 14 days per Brewers Association guidance (our Veracity™ C-DLC is a heavy-duty option built for this cycle). Acid cleaner targets beer stone (calcium oxalate) and mineral scale that alkaline cleaner can't dissolve; run it every 3–6 months as a supplemental deep clean, not a replacement for the alkaline cycle.
Why does Draftec Blue Dye cleaner turn the solution blue?
The blue color is a visual indicator: once you see solid blue coming through the line, you know cleaner has fully displaced the beer and reached the faucet. It takes the guesswork out of a manual clean and makes it easy for staff to confirm the job's actually done, not just started.
Do I need a no-rinse cleaner, or should I always rinse after cleaning?
Standard alkaline and acid cleaners need a full water flush after soaking — residual cleaner in the line will affect beer flavor. No-rinse formulas (like our Powdered Super No-Rinse Line Cleaner) are designed to be safe at low residual concentration, which saves a step for high-volume operations, but always follow the product's label directions rather than assuming either method.
Liquid or powder cleaner — which should I use?
Liquid cleaners (like BLC Line Formula) are ready to use and convenient for single kegerators or direct draw systems with a cleaning can. Powder cleaners are more economical per cleaning at volume — a 40 lb pail covers far more cycles than the equivalent liquid — and make sense once you're running a recirculating pump program across multiple lines.
What happens if I skip line cleaning or stretch past 14 days?
Beer stone and biofilm build up fast — most operators see off-flavors, excess foam, and pour inconsistency within days of missing a cycle, and bacterial contamination risk climbs the longer it's skipped. The Brewers Association's 14-day standard exists because that's roughly the window before buildup starts affecting what's in the glass.
Also Cleaning Faucets or Couplers?
A full cleaning cycle includes more than the lines. See our Draft Beer Faucets collection if yours need replacing, and Keg Couplers for coupler-specific parts and cleaning adaptors.
