1. Dissolve 50 grams (3 tablespoons) of metabisulphite powder in 4 litres (approximately one gallon) of cool water.

2. Submerge or spray all pieces of equipment with solution.

3. Rinse thoroughly with cool water and drip dry. You can store leftover sulphite solution for two months in a tightly sealed container.

Now that deserves a cheers!
