How to Sanitize with Sodium Metabisulfite

Sodium metabisulfite is commonly used in homebrewing and winemaking for sanitizing equipment. Here’s how you can safely and effectively sanitize with it.

Materials Needed

  • Sodium metabisulfite powder
  • Clean water
  • Spoon or measuring tool
  • Buckets or containers for mixing and soaking
  • Protective gloves and eyewear (recommended)

Mixing the Solution

  • Dissolve 1 tablespoon (about 15 grams) of sodium metabisulfite in 1 gallon (about 4 liters) of warm water.
  • For smaller amounts, use 1 teaspoon (about 5 grams) per quart (about 1 liter) of water.
  • Stir until completely dissolved.

Sanitizing Procedure

  • Rinse the items to remove any debris or residue.
  • Submerge the equipment in the sodium metabisulfite solution, ensuring all surfaces contact the liquid.
  • Let the equipment soak for at least 10 minutes.
  • Remove the items and allow them to drain. Rinsing with clean water is optional, but often recommended to avoid any residual odor or taste.

Safety Tips

  • Avoid inhaling the fumes as they can be irritating.
  • Use gloves and work in a well-ventilated area.
  • Keep sodium metabisulfite out of reach of children and pets.

Storage and Disposal

  • Store leftover solution in a sealed container for up to a few days.
  • Dispose of used sanitizer by pouring down the drain with plenty of water.

Always follow safety instructions and guidelines specific to your equipment and usage.
