Chemical Dilution Chart

Use this chart as a guideline for diluting chemical cleaning products. 1:x means 1 part concentrate to x parts water. For example, to make a quart of solution in a 1:15 dilution, mix 2 oz. of concentrate into 30 oz. of water. (NOTE: To minimize foaming, fill the container with water before adding the concentrate. Then stir thoroughly.)

Before we get started, here is a simple conversion chart:

Conversion Chart
1 Gallon 128 ounces 1/4 Cup 2 ounces
1 Quart 32 ounces 1/8 Cup 1 ounce
1 Pint 16 ounces 2 Cup 1 Pint
1 Cup 8 ounces 2 Pints 1 Quart
1/2 Cup 4 ounces 4 Quarts 1 Gallon

And the dilution chart:

  1. Great chart. This is sooooo important. So many people over use chemicals and detergents when cleaning because they do not understand how mix rations work or how to convert them. Its not only dangerous but a huge waste of money.
