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:
