Shelf-Stable Laundry Cleaning Formula

Used to clean, deodorize, and soften clothes in hand-wash or machine-wash settings without commercial detergents.

This shelf-stable, non-toxic laundry powder combines sodium bicarbonate with other natural ingredients to lift stains, neutralize odors, and improve water softness. It’s easy to mix in bulk and store for long-term use in off-grid or preparedness environments.

Ingredients (Makes Approximately 10–12 Cups)

  • 2 cups sodium bicarbonate (baking soda)
  • 2 cups washing soda (sodium carbonate)
  • 1 bar Castile natural soap, grated finely (castile, lard, or tallow soap preferred)
  • Optional: 10–15 drops essential oil (e.g. lavender, tea tree, lemon)
  • Optional: 1 cup borax (only if preferred and available) — it can enhance stain removal and odor control, especially in heavily soiled laundry, but may be avoided by those with sensitive skin or concerns about long-term exposure to mineral-based additives.

How to Make It

  • Grate the bar soap using a fine cheese grater or food processor
  • In a large bowl or container, combine grated soap, baking soda, and washing soda
  • Stir thoroughly until evenly mixed
  • Add essential oil (if using) and mix again
  • Store the mixture in a sealed, dry container with a scoop

How to Use It

  • Machine washing: Use 2–3 tablespoons per load
  • Hand washing: Use 1–2 tablespoons per basin of warm water
  • For extra softness or deodorizing, add ¼ cup white vinegar to the rinse cycle (separately)

Storage & Shelf Life

  • Store in a sealed container away from moisture and strong odors
  • Shelf life is indefinite if kept dry
  • Label clearly and keep out of reach of children and pets

When to Use It

  • For regular laundry in preparedness or off-grid homes
  • When commercial detergents are unavailable or undesired
  • To reduce chemical exposure and maintain self-reliant hygiene systems
  • As part of a long-term, DIY cleaning supply stockpile
