At Chemical Guys, we make two types of products: Ready to Use, and Full Strength. When products come full strength, you can dilute them to suit your cleaning needs to get more bang for buck and make the products last longer. For example, a 10:1 ratio means you mix 10 parts water to 1 part chemical. The amount of each liquid changes depending on the ratio used, and the size of the container. Use the Chemical Guys Dilution Ratio Chart to dilute your favorite Chemical Guys products. Simply mix the proper amounts of product and filtered water to achieve the perfect dilution ratio to take on any job.
