How To Make A Disinfectant Spray & Antiseptic Wash From Bleach

Disinfectant & Antiseptic Wash From Household Bleach

Used mainly to clean and disinfect toilets and sinks, basic household chlorine bleach is very cheap, easy to obtain and it kills almost all known germs and most viruses, including coronavirus. Basic household bleach (not perfumed or thick bleach etc) can be diluted and used to make a powerful spray/surface disinfectant. It can also be used to make an antiseptic wound wash known as Dakin’s Solution. Below you will find the widely used ratios and ingredients for both solutions.

We have also done a how to make germ and virus-killing homemade disinfectant wipes post. Additionally, if you are looking for hand wash or hand sanitizer, but they also sold out in the shops, check out our simple DIY hand sanitizer post and our dish soap DIY foaming hand wash post.

How To Make A Disinfectant Bleach Solution

Safety

  • Bleach emits toxic fumes. Mix the solution outdoors or in a well-ventilated space.
  • Never mix bleach with ammonia, alcohol, vinegar or other acids as doing this can create toxic gases that can be fatal.
  • Wear rubber gloves and avoid getting bleach on your skin or clothes.

Bleach Disinfectant Recipe

  • Clorox or similar household bleach (Sodium hypochlorite solution 5.25%). Don’t use thick or scented bleach.
  • Tap water
  • A mixing/measuring jug
  • An old thoroughly rinsed out plastic spray bottle

How To Make Bleach Disinfectant Spray

The bleach to water ratio is 1:10.  That’s 1 part bleach for 10 parts water.

Coronavirus:  The CDC state that 5 tablespoons (1/3rd cup) bleach per gallon of water or 4 teaspoons bleach per quart of water is effective against coronavirus.

  • Measure out the amount of water required.
  • Measure out the amount of bleach needed (1:10 ratio based on the amount of water).
  • Add the water and bleach to the mixing jug and carefully mix.
  • Carefully pour the mixed solution into a plastic spray bottle and use to disinfect surfaces as required. Be sure to label the bottle as bleach disinfectant!

There is some debate as to how long this disinfectant solution remains effective as it loses disinfectant power quickly when exposed to heat and sunlight. With this in mind, it seems sensible to make small batches daily and discard any leftover.
