Karcher's revolutionary new SoapPacs offer the easiest way to use detergents with any pressure washer. These self-dissolving SoapPacs are pre-measured to make sure you use just the right amount each time. Our Concentrated Vehicle Wash & Wax contains a special blend of water-reactive polymers and waxes that give your vehicle that just-waxed look with each use. Washing agents gently remove dirt and debris, leaving behind a shiny, freshly waxed appearance upon rinsing. Contains 12 SoapPacs. Makes 3 gallons of full strength, ready-to-use Vehicle Wash & Wax. 100% biodegradable. Videos demonstrating how to use SoapPacs are available in our Video Library.
