Thank you for the advice...... much appreciatedGrowlers are far from garbage, but if they are going to be a spare set that you won't be running for a while, give them a good wash, scrub them with soap & water and a stiff bristle brush. Wrap each one in a black garbage bag, store them out of the elements especially sunlight.
Also after washing them a good coat of a non silicone wax will really help preserve them. A simple wax is actually plain lemon pledge furniture wax.
