Cleaning Growlers

Growler Cleaning: 

Rinse well.

Growler cleaning in more detail:

Keeping your growler clean is very simple. 

Directly after use, rinse with hot water and air dry.

Soap is not recommended as it can leave a residue in the growler that can cause off-flavors and undesired effects on the beer. 

If you do choose to use soap, use a soap that is unscented. 

If you use a brush make sure that it is a soft brush that will not scratch the inside of the growler.

Growlers can be sanitized. After a hot sanitization, rinse with cold water before filling, especially if you are not a fan of warm beer.

If you need to remove some funk try a little salt and lemon. 

And in the end, make sure to rinse it well.
