Mix together 2/3 cup of white vinegar with 1/2 teaspoon of Dawn dish soap in a glass measuring cup. Fill the rest of the measuring cup with hot water. Place your makeup brushes in the measuring cup and allow them to soak for 5 minutes. Remove the brushes from the solution and rinse with cold water until the water runs clear.
My laundry detergent recipe: 1 bar kirks castile soap 1 cup washing soda 1/2 cup baking soda Coarsely chop soap into pieces and pulse in food processor until powdered. You can do up to 4 bars at once. Add sodas. Use 2 tbsps per load. This stuff really works wonders on our muddy, smelly farm clothes.
