Review on 🚿 Zep All-In-1 Premium Pressure Washing Concentrate (172 Fl. Oz/5.09L): Ultimate Cleaning Power for All Surfaces! by Teresa Torma

I mainly use this for car washes. Place in a foam gun on a pressure washer, mix about 10 parts water to 1 part Zep. The frother dilutes it with another 7 parts water to 1 part Zep. Spray on the car, wait about 4-5 minutes, wash with a pressure washer. Dry the windows so they are free of water stains and allow the paint to air dry. The car looks about 95% after a full hand wash/dry. I wash 4 cars in less than 20 minutes - line them up and work in a row, rinsing one off while the next soaks. For comparison, I've tried several other soaps, including the high-end Chemical Guys and Meguiar soaps. They don't come close and all require a hand wash to achieve an equivalent level of cleanliness.
