Titration Titration is a common laboratory method of quantitative chemical analysis that should be performed at your car wash. Titration is used to determine the unknown concentration of an identified chemical species. Since volume measurements play a key role in titration (in the car wash industry it is also known as volumetric-metrics),  concentration should be monitored regularly and to maximize the cleaning process . Concentration levels are determined by the chemical used and as recommended by the chemical manufacturer.

Flow Testing Flow testing is measuring how much final solution is used in each application of the vehicle cleaning process and is achieved by adding an inline flow meter to each output line or visually measuring solution used from tank after each pass. Flow testing is a good practice that can help you control consumption, efficiency and costs.

How Often Monthly Titration and Flow Testing is recommended with semi-monthly being the best practice. These tests should be performed when noticing a change in cleaning results and when changing brands. Consult with your D&S Authorized Distributor for specific recommendations.

Benefits Regular Titration and Flow Testing will keep your car wash running at peak performance, delivering clean vehicles and happy customers and can periodically uncover components in your car wash that may need maintenance such as clogged or broken injectors, faulty pressure regulators, or solenoids.
