Ultrasonic fuel injector cleaning and flow testing is the only fuel injector cleaning method that guarantees reliable and measurable results. No other injection cleaning method can claim such results. The goal of fuel injector cleaning is to remove hydrocarbons and deposits from the internal components of the fuel injector.
Even with the proper tools, professional fuel injector cleaning equipment and specialized ultrasonic cleaning solutions it takes approximately 45 – 60 minutes to thoroughly clean the injectors. GDI or Direct Injection fuel injectors takes even longer.
