Preparation
- Ensure your workspace is clean and organized for safety.
- In a large pot, combine used oil and caustic soda flakes, stirring gently.
- Slowly add 20 liters of water, stirring continuously in the same direction.
- Heat the mixture until it boils, stirring consistently.
- Stir for at least an hour until the mixture thickens and foams.
- Check if the mixture drizzles off a ladle like honey for readiness.
- Turn off the heat and allow the soap to cool for one to two weeks.
- Once hardened, cut the soap into desired shapes and store in a cool, dry place.
Notes
Always wear gloves and protective eyewear when working with caustic soda. Feel free to add essential oils for fragrance or experiment with different oils or colors for unique results.
