Is the sodium carbonate for raising pool PH the same as the sodium carbonate in washing soda? I read the label and it was talking about how caustic it is so I wanted to make sure.
Simple Washing Powder
16 cups baking soda
12 cups borax
8 cups grated castile or glycerin soap flakes*
3 tablespoons lavender, lemon, or grapefruit essential oil
Combine baking soda, borax, and soap flakes, add essential oil, and mix with a wire whisk. Use 1/8 cup of powder per load. This recipe makes enough powder to last a family of four one year.
