1. **Grate the soap bar** using a cheese grater or food processor.
2. **Dissolve** the grated soap in about 4 cups of hot water over low heat, stirring until fully melted.
3. **Add 1 cup of washing soda** and stir until fully dissolved.
4. **Pour** the mixture into a large container (like a gallon jug or old detergent bottle), then add enough warm water to make about 1 gallon total.
5. **Add essential oils**, if using, and shake or stir well to combine.
6. Let it sit for 12–24 hours. It may thicken or gel — just shake it up before each use.
