Other Types of Bar Soap

I have not tried other types of bar soap in this recipe but you may want to try something like Kirk’s Castile Soap or Zote White Laundry Bar Soap if you would like.

If you or someone in your family has sensitive skin, then consider using a natural laundry bar like Mom’s Laundry Cube Soap Bar.

Equipment and Ingredients

Small Batch Ingredients:

  • 1 Bar of Grated Soap
  • Borax – 2 Cups
  • Super Washing Soda – 2 Cups
  • Oxi-Clean or Store Brand – 2 Cups (optional)
  • 40 drops of Essential Oils (optional)
  • For Hard Water add 2 Cups of Baking Soda
  • Carefully mix to combine and store in a sealed jar

Large Batch Ingredients:

  • 3 Bar of Grated Soap
  • 1 Box of Borax (4lbs size)
  • 1 Box Super Washing Soda (3lb 7oz size)
  • 1/2 container of Oxi-Clean or Store Brand (optional)
  • 2 teaspoons of Essential Oils
  • For Hard Water add 1 Box Baking Soda (4lb size)
  • Carefully mix to combine and store in a sealed jar


  • Grate a bar of soap into flakes using a box or hand grater into a bowl, whatever you have available. You can grate more than one bar; it just depends on how much laundry detergent you’re planning to make either a small batch or large batch
  • In a separate container, mix together borax, washing soda, baking soda, & Oxi-Clean.
  • Add the grated soap to this mixture
  • Add essential oils if desired.
  • If you wish to make more, you can increase the quantity as long as you’re keeping the ingredients in the right proportion.
  • Thoroughly stir the ingredients together and there you have it; your homemade laundry detergent is ready to use.
  • Store in a sealed jar or container with a scoop.
  • Use 1 to 2 tablespoons for small loads of laundry
  • Use 4 to 6 tablespoons for large and/or dirty loads of laundry


  • You can also take it a step further and mix small amounts of the ingredients in a food processor to create a fine powder that will easily dissolve even in the coldest water.
  • Once the ingredients have been blended together, wait for the particles to settle down before taking off the lid to avoid inhaling them.
  • I like mixing the ingredients outdoors to prevent breathing any particles
  • Only process small amounts at a time and then pour into your container.
  • Use around 2 tablespoons for a small load or about 4 to 6 tablespoons for large or dirty loads.
  • You may have to use more if you’re working with hard water.

  • If you want your laundry detergent to have a fresh and long-lasting scent, consider adding Purex Crystals. (but, if you staying more natural then look at the next tip)
  • You can also create your own naturally scented crystals with essential oils and use them instead of the Purex crystals. The ones that I like are orange, lemongrass and lavendar.
