The Centers for Disease Control and Prevention (CDC) recommends that you use a solution of 1 tablespoon (1/3rd ounce or 8.75 ml) of bleach per gallon (4 liters) of water to sanitize surfaces. This ratio equates to approximately 4 teaspoons (1 tablespoon) of bleach per quart (1 liter) of water.
If you’re looking for a quick and easy way to sanitize your home, bleach is a great option. But how much bleach should you use per cup of water?
The answer really depends on what you’re trying to sanitize.
For general cleaning, a ratio of 1:100 (one part bleach to 100 parts water) is typically sufficient. But if you’re trying to disinfect surfaces or remove mold and mildew, you’ll need to use a stronger solution of 1:10 (one part bleach to 10 parts water). Of course, always be sure to read the labels on your bleaching products and follow the manufacturer’s instructions.
And when using any kind of chemicals, it’s always best to take precautions like wearing gloves and ventilation.
How Much Bleach Do I Put in 2 Cups of Water?
When it comes to bleach, there is no one-size-fits-all answer. The amount of bleach you need to add to water depends on the concentration of the bleach and the type of water you are using.
If you are using a standard household bleach that is 6% chlorine, you can use 1/2 cup (120 ml) of bleach in 2 cups (480 ml) of water.
This will give you a 0.3% chlorine solution, which is the recommended ratio for disinfecting surfaces. If you are using a more concentrated Bleach like Clorox® Regular Bleach₂ with CLOROMAX®, which has 8.25% chlorinated, then 3/4 cup (180 ml) should be used per 2 cups (480 ml) of water to make a 0.3% chlorine solution. It’s important to note that these ratios apply to diluting liquid bleach in clean, fresh water only.
You should never mix bleaches together or add other chemicals to your bleach solutions as this could create dangerous fumes or even explosions.
How Much Bleach Do I Use for 5 Cups of Water?
Assuming you are using a standard household bleach that is 3-6% sodium hypochlorite, and you want to make a 0.1% solution:
For 5 cups (40 fluid ounces) of water, you would need approximately 1/8 teaspoon (0.625 ml) of bleach.
To make sure you have made a 0.1% solution, take the container of water and add the desired amount of bleach to it.
In this case, that would be 1/8th tsp or 0.625 mL. Once the bleach has been added, stir well and then check the concentration using a test strip or drop counter.
How Much Bleach Do You Put in a Gallon of Water to Make It Drinkable?
Assuming you are using regular bleach (5.25% sodium hypochlorite), the CDC recommends adding 1/8 teaspoon (~0.75 ml) of bleach to 1 gallon of water. This ratio will produce a disinfected solution with a chlorine concentration between 50-200 ppm (parts per million).

How Much Bleach Per Gallon of Water to Sanitize
If you’re looking to sanitize surfaces or objects with bleach, it’s important to know how much bleach to use in relation to the amount of water. The CDC recommends using a 1:49 ratio of bleach to water, which equates to 1/3 cup of bleach per gallon of water. This solution should be used within 24 hours for best results.
If you’re looking to sanitize with bleach, the CDC recommends using a 1:50 ratio of bleach to water. That means you’ll need 1/2 cup of bleach for every gallon of water.
