How to Make 1/4 Strength Dakin’s Solution: A Comprehensive Guide

Dakin’s Solution, also known as Dakin’s Fluid or Carrel-Dakin Solution, is a disinfectant commonly used to clean wounds and prevent infection. It was developed by an American surgeon named Henry Drysdale Dakin in 1915. This solution is made by mixing bleach with water and adjusting the concentration to meet specific needs.

While the original Dakin’s Solution is made with full-strength bleach, 1/4 strength Dakin’s Solution is often recommended for less severe wounds or when using the solution for longer periods. In this article, we will guide you through the process of making 1/4 strength Dakin’s Solution and answer some frequently asked questions.

– Household bleach (containing 5.25% sodium hypochlorite)
– Sterile water (distilled or boiled water)

– Clean measuring cup
– Clean measuring spoons
– Clean mixing container (glass or plastic)
– Sterile container for storage (dark glass bottle or plastic container)


1. Start by thoroughly cleaning all the equipment you will be using. This step is crucial to ensure the solution remains sterile and safe for use.

2. Measure out the desired amount of sterile water. You can use either distilled water or boil tap water for at least five minutes and let it cool down before using.

3. Using the measuring cup, pour the pre-measured water into the mixing container. This will serve as the base for your 1/4 strength Dakin’s Solution.

4. Measure out the appropriate amount of household bleach. To make 1/4 strength Dakin’s Solution, you will need to mix 1 part bleach with 3 parts water. Therefore, for every 1 cup of water, add 1/4 cup of bleach. Use the measuring spoons or cup to achieve accurate measurements.

7. Once the solution is well-mixed, carefully pour it into a sterile container for storage. Dark glass bottles or plastic containers are preferred, as they can help protect the solution from degradation caused by light exposure.

8. Label the container with the date of preparation and the concentration of the solution. It is essential to keep track of the solution’s expiration date, which is usually around two weeks from the date of preparation.
