10- Rubber Ducky is a heavy based cleaner for vehicle exteriors.
An aggressive vehicle cleaner with a high foaming surfactant that's made to remove road grime, dirt etc, leaving a streak free, high sheen finish.
 
Directions:10-4 Rubber Ducky can be used at a ratio of between 1:40 (2.5%) and 1:100 (1%). If you are foaming from a bottle at the gun handle - use neat.
Spray/brush/foam on detergent, let rest on the surface then high pressure rinse off - then do a final rinse. If the vehicle is particularly bad, some brushing can help obtain the best result.
