Cleaning The Growler

  • Rinse your growler by filling it to the top and then emptying halfof the water. Shake the remaining water around inside the growler and pour out the rest.
  • Add the packet of PBW to the empty growler, and re-fill with warm water, replace the cap and shake (cartridge holder can be washed separately. Caution: warm water and PBW will create pressure inside the growler! Prior to opening either open the tap (recommended) or pull the zipper tab on the safety valve to release the internal pressure!
  • Let the solution sit for 30 minutes.
  • Remove cap and empty your growler (if you hold the growler with the tap facing down, some water will also run from the tap.
  • Fill the growler with clean tap water and rinse thoroughly.
  • Allow the growler to dry with the cap removed prior to the first filling.

Sanitizing Your Growler

Sanitize with Star San or another acid-based sanitizer as per the markers recommendations as part of your regular cleaning regiment.  This has the added benefit to establish a uniform passive oxide layer that will maximize corrosion resistance.

Storing Your Growler

Beer and beverage residue not thoroughly cleaned leaves organic and nonorganic residues and microorganisms. The better your growler is cleaned the less chance you will have microbial growth (such as mold).

Your growler is air tight, so stored with the cap off or loose will help reduce the surface population of microorganisms. Rinse your growler thoroughly with water prior to each use. You can purchase individual pre-measured packets of PBW for an occasional cleaning or if the growler has been stored for a long period of time. It is recommended you sanitize with Star San, or similar prior to filling.

Tap Cleaning

A common problem with beer taps of every type is dried beer residue is sticky.  If your tap is stuck, the golden rule is not to use excessive force to try to open the tap as this can damage your tap.  Preventive maintenance is best, which is thoroughly rising the tap, including holding it under the sink and opening and closing the tap.  If the tap is stuck rising under hot water should open the tap.  If not, then you can remove the neck nut, take off the tap and soak it in a bowl of PBW. Then rise thoroughly.   

using a wrench to remove the neck and tap assembly from our co2 pressurized growler.

Sight Level Cleaning

If you unit has a built-in tap, included is a sight level. With thorough rising and sanitizing after use, you won’t need to take the sight glass apart.  If you do, the level, and the tap, can be more thoroughly cleaned by occasionally completely removing the Neck Nut and following these steps.

loosening the pipe unit to get the sight glass out from the tap assembly.
Removing the pipe unit from the pressurized growlers sight glass tap assembly.
Tap assembly components from the pressurized growlers that need to be cleaned and maintained.

Be mindful that if the unit is not sealed properly when replaced, there is a potential for gas leaking. This will be fairly obvious the next time the growler is pressurized (it might leak gas or beer). However, removal and replacing is fairly straightforward. Components should slip easily into their original position without force, and the neck nut tightened by hand until the last couple quarter turns with a crescent wrench to seal the gasket to the top of the pipe unit.


Do not use chlorine bleach or chlorine-based products which can damage your growler’s surfaces. Do not use Scotch-Brite pads or stainless-steel scrubbing pads on the interior or exterior as these will damage the surface and potentially produce rust. Use soft terry cloth.

Exterior Care Of Your Growler

Exterior surfaces can be polished with household appliance stainless steel and brass polishing products as per the manufacture’s recommendations. Always use only soft cloth.
