The secret to looking after your growler is washing it immediately after use. Here’s a little step by step.

1. Put the growler under the tap and turn on the hot water.
2. Thoroughly wash the growler’s insides with the hot water. An all plastic brush can help.
3. Remove the plastic sealer on the lid and wash around that and where it attaches to the lid.
4. Turn the growler upside down and let it dry in a dish rack along with the sealer.
5. When it is completely dry, store it with the lid off. Better yet, go fill it up again with your favorite craft beer.
