Formula Clean Iron/Fall out remov comes pre-diluted to the correct strength for safe exterior use. In all cases, wash and rinse the surfaces you are going to treat in the normal way and allow to dry.
Next, spray the product on liberally. As any iron contaminants dissolve into solution, the initially colourless liquid will gradually turn purple over a period of 1-2 minutes.
Although Formula Clean Iron is essentially a touchless cleaner, you can agitate it with either a microfibre towel or a brush if needs be. After 1-2 minutes, or once the dark purple solution has dried fully, thoroughly rinse the surfaces you have treated with a strong stream of water. If you let the solution dry fully, you may need to use a stronger jet of water from a pressure washer to remove the hardened film.
