How To Use Bleach As A Disinfectant

Chlorine bleach or sodium hypochlorite is a powerful disinfectant used in many households and facilities. This chemical compound is effective in killing microorganisms that cause diseases and infections. Bleach is inexpensive and readily available in stores, which is why they are widely used as a disinfectant. However, bleach is also hazardous because it is highly corrosive. It emits fumes that may be dangerous to your health, which is why bleach should never be used in full-strength. Learn how to use bleach as a disinfectant using the Center for Disease Control or CDC’s recommended 1:10 solution.

Supplies Needed

  • Household bleach
  • Plastic spray bottle (quart-sized or larger), or glass jar with lid
  • Damp cloth
  • Measuring cup
  • Water

Steps in Making the 1:10 Solution

1:10 solution basically means, 1 part bleach for every 9 parts of water. However, if you need a smaller amount, you can start with ¼ cup bleach for 2 ¼ cup water. If you need a larger amount, you just need to increase the amount of water and bleach solution accordingly. For instance, for ½ cup bleach, use 4 ½ cups water, and for ¾ cup bleach, use 6 ¾ cups of water. Use measuring cup for accurate measurement.

1. Pour the bleach to the spray bottle or glass jar before adding water. This is done in order to prevent bleach from splashing to you.

2. Use cool water for the solution as hot water decomposes the active ingredients of bleach and may lose its disinfectant power.

3. Replace lid on container.

4. Gently invert the container back and forth to mix the solution.
