Bleach is a powerful cleaner that is able to disinfect and sanitize all kinds of surfaces. We use a cleaner with water to make a solution. However, have you ever been in a situation where the bleach did work probably as advertised or the solution damaged your facilities? Some kinds of cleaner can be excessively harsh if it doesn’t dilute with a sufficient amount of water. Else, it may be out of function if diluted with too much water. Understanding the necessity of bleach dilution, Sparkling and Beyond will introduce you to some common-using bleach-to-water ratios for spray bottles and explain how to calculate the solution for each type of spray bottle. 

What is the dilution ratio?

The dilution ratio is a ratio that indicates how many parts of the concentrated product should be to be diluted to how many parts of the dilutant or extender (usually water or a solvent). For example, 1 ounce to a gallon (128 ounces) would be 1:128, not 128:1. This ratio is different between bleaches.

Caution: Since bleach can be harmful to your skin, it is better that you do anything with gloves and a mask. 

Metric calculations such as liters can also be calculated. You just need to convert the metric figures to gallons or ounces prior to starting. Common metric volume measurements and their English equivalents are listed below:

  • 1 quart = 0.946 mL
  • 1 gallon = 3.785 liters
  • 1 liter = 0.264 gallons
  • 4 liters = 1.056 gallons

How To Calculate Dilution Ratios Of A Spray  Bottle?

Let’s take an example you want to make a X oz spray bottle with the 1:4 dilution ratio (1 part of chemical and 4 parts of water). X is the maximum amount of liquid that the bottle can contain. Now, you must make clear how much water and chemical should be used in this case. Follow the steps below: 

Step 1: Find how many parts we will have when mixing the solution. Let’s move on with the above example with the measurement unit is ounce, a dilution ratio is  1:4 so we would need 1 part (water) +4 parts (bleach)= 5 parts in total.

Step 2: As you divide  X oz into 5 parts, each part will be X/5 oz. 

Step 3: As the dilution ratio is 1:4

=> the water you need: 4 * X/5 = 4X/5
=> the chemical you need: 1 *X/5 = X/5

There are some common volumes of spray bottles. With our above instructions, you may now calculate and make a solution by yourself. If you have not clearly understood the recipe, let’s check another example: 

Bleach to water ratio for 32 oz spray bottle with the dilution ratio of 1:4: 32/5 = 6.4 oz/part water needed: 4 * 6.4 = 25.6 oz bleach needed: 1 * 6.4 = 6.4 oz=> Total: 25.6 + 6.4 = 32 ozBleach to water ratio for 12 oz spray bottle with the dilution ratio 1: 512/6 = 2 oz/part water needed: 5*2 = 10 oz bleach needed: 1 * 2 = 2 oz=> Total: 10 + 2 = 12 oz
Bleach to water ratio for 24 oz spray bottle with the dilution ratio: 1:424/5 = 4.8 oz/part water needed: 4*4.8 = 19.2 oz bleach needed: 1 * 4.8 = 4.8 oz=> Total: 19.2 + 4.8 = 24 ozBleach to water ratio for 16 oz spray bottle with the dilution ratio: 1:416/5 = 3.2 oz/part water needed: 4 * 3.2 = 12.8 oz bleach needed: 1 + 3.2 = 3.2 oz=> Total: 12.8 + 3.2 = 16 oz
Bleach to water ratio for 28 oz spray bottle with the dilution ratio: 1: 428/5 = 5.6 oz/part water needed: 4 * 5.6 = 22.4 oz bleach needed: 1 * 5.6 = 5.6 oz=> Total: 22.4 + 5.6 = 28 ozBleach to water ratio for 25 oz spray bottle with the dilution ratio: 1:425/5 = 5 oz/part water needed: 4*5 = 20 oz bleach needed: 1*5 = 5 oz=> Total: 20 + 5 = 25 oz
  • How To Calculate Dilution Ratios Of Gallon Containers: Basically, a gallon is 128oz. The process is exactly the same as the 32 oz way.

A common mistake in calculating how much-diluted bleach will result from a fixed ratio is forgetting to add the amount of the concentrate to the total. For example, 1 ounce of a product diluted at 1:64 makes 65 ounces, not 64. This includes not only the 64 ounces of dilutant but also the original 1 ounce of concentrate.

Summary

Sanitizing products with a variety of dilution ratios may make failure if used indiscriminately. Being aware of how to calculate bleach to water ratio for spray bottles properly is a must for people who choose bleaches to sanitize or disinfect their home facilities. However, mixing chemicals seems not an easy task for everyone. if you are not familiar with this, why don’t you give Sparkling and Beyond a call for further help?
