The cleaner is applied at 2% to 5% strength to clean surfaces and objects using a foam gun, spray lance or pressure washer. Application of the concentrate is performed using a foam gun. The cleaner can be used with cold or warm water; hot water facilitates cleaning and shortens the time needed for the cleaner to take effect. Depending on the degree of soiling and stability of the foam, allow the cleaner to take effect for at least 15u201360 minutes. The cleaner should not be allowed to dry; wet surfaces and objects again with cleaning solution or water if necessary. Then rinse off dirt and detergent residues thoroughly using a water jet.
