Bleach is a great disinfectant for cleaning hard surfaces in your home. To disinfect a surface, mix 1 part bleach to 9 parts water, and spray the solution on the surface to be cleaned. Let the surface sit for 30 minutes, and then wipe it clean with a cloth or a piece of paper towel. For extra disinfecting power, you can add 1 teaspoon of ammonia to the bleach solution.
