The Karcher pouch contains 500ml of concentrated detergent which can be diluted with 4.5L of water to make 5L of ready-to-use detergent. The pouch uses less shelf space and is easier to carry and transport. The solution is for use in a detergent tank or can be used with a detergent suction hose. This formula is for use on vehicles and helps to cut through road grime while the wax helps to protect paint work and leaves it gleaming.
