Sulfur Sticks are used to sterilize barrels for long term storage.
First, the barrel is emptied and allowed to dry completely. The stick is suspended in the barrel and burned. The stick can be suspended with a mono-filament fishing line. After, the barrel is bunged, and stored.
Dosage: 1 stick per 60 gallon barrel per month. Barrels should be treated once per month for long term storage.
