How Much to Use:

  • Use 1/4 to 1/2 cup per load, depending on your machine and the type of laundry.
  • Adjust the amount based on the size of your machine and the level of soiling.
  • Front-loading washers may require less soap compared to top-loading washers.
  • Consider water hardness and fabric type when determining the appropriate amount of soap.

Vinegar Rinse Instead of Fabric Softener:

  • Fabric softener is not recommended with homemade laundry soap.
  • Use a 50-50 mixture of vinegar and water in your fabric softener dispenser to soften fabrics and keep your washing machine clean.
  • Avoids fabric softener buildup and maintains fabric absorbency.
