How to Use Bleach to Clean Safely and Effectively

The heavy scent of bleach in the air must mean that something is really clean, right? Not necessarily. Bleach may be great for a lot of things, but cleaning is, technically, not one of them. Should you try cleaning with bleach, and can bleach have other benefits in your home? 


First, bleach is a disinfectant, not a cleaner. Bleach does a fantastic job of killing germs; it removes tough stains and whitens clothing.

Bleach doesn't clean dirt and residue from surfaces. To do that, you'd need to scrub and rinse the surfaces first, and then apply a bleach solution.

Most of us smell bleach and think that it is cleaning a surface, but really, it is probably being used to disinfect the surface instead. For example, many people use bleach in their bathrooms to wipe down their toilets and bathtubs. Those are areas that are prone to germs. If there was a stain on a sink, the bleach may not remove it, but it would kill any germs on the surface.


For many household cleaning jobs, bleach just isn't the right cleaning solution. It has heavy fumes that can make you sick. Contact with bleach on your skin is irritating and can be very harmful. Mixing it with many other cleaners can produce toxic results. Bleach can also damage surfaces and remove color.

Bleach is a good disinfectant and stain remover but not a great general cleanser. So how can you use it in your home? Are there some instances where it is better to use than others?


Here are a few tips for safer bleach cleaning:

  • Dilute the bleach with water for safer cleaning. It can be poured into a washing machine, but it will eventually be diluted with water there.
  • Clean a surface first before you begin sanitizing. Use detergent and water to clean a surface, and then use bleach and water to disinfect it. Let the bleach/water solution contact the surface for at least 5 minutes. Then rinse it off and air dry it.
  • Color-safe bleach uses hydrogen peroxide to help remove stains instead of sodium hypochlorite or chlorine. It can brighten colors.
  • Household cleaning products often are made of chlorine bleach. There are other types of bleach, such as peroxide bleach.
  • Bleach is used to whiten clothing. It can also remove mildew and mold. 
  • The dilution should be about 1 tablespoon of bleach to 1 gallon of water, or one part of bleach to 10 parts of water.


If you use hot water with bleach, it can release chlorine gas that can be harmful. Don't mix it with household chemicals such as vinegar or ammonia, as it can cause unsafe reactions.
