Karcher 9.558-112.0 Pressure Washer Vehicle Wash and Wax SoapPac, 12-Pack
I bought this Karcher Pressure Washer Vehicle Wash and Wax SoapPac for my Dirt Devil Pressure Washer and Wet/Dry Vacuum System. The packets dissolve in water like the type we use in the dishwasher. I just dissolved one in each tank and washed, then dried with towels. The windows had streaks from the towel drying, but the car was otherwise clean and free of marks — a satisfactory result. It takes less than one tank to clean my car, which makes this an economical choice for my car washing needs.
