How Much Sodium Metabisulfite to Sanitize

To sanitize equipment with sodium metabisulfite, a common method is to mix:

  • 1 tablespoon (about 15 grams) of sodium metabisulfite
  • with 1 gallon (3.8 liters) of water

This solution is used to sanitize winemaking, brewing, or food processing equipment.

Instructions

  • Dissolve the sodium metabisulfite completely in water.
  • Soak or rinse the equipment with the solution.
  • Let it stand for at least 2 minutes for effective sanitation.
  • No rinse is necessary for most uses, but allow equipment to air dry.

Note: Always use in a well-ventilated area, as fumes can be irritating.
