When Stars & Stripes touch-less soap blends on the vehicle surface, a resulting pH shock will activate the cleaning reaction. This dual stage process breaks the bond of dirt and road film from the surface, allowing the high psi rinse to remove more grime than any single stage application and also results in a neutral pH. This process saves you up to 80% of the time it would normally take to do a mitt wash. Using two soaps also lets us tackle more grime by giving us more dwell time as we as allowing us to use a wider range of surfactants that help with many different types of grime. No situation is the same in the world washing and degreasing. Different seasons, paint conditions, power washers, etc all play a huge role in how you wash. Our 2 stage soap arrives SUPER concentrated. We recommend a ratio of 4:1 to start. Wash a small section and adjust your soaps if needed. Use this technique when ever starting a new wash.
