The two step system was popularized by a major equipment manufacturer and field-tested for many years. The first step, No. 1, is a hydrofluoric acid product that sets the magnetic attraction of the soil. The second step, No. 2, is an alkaline chemical that reverses the attraction and repels the soil from the surface. Step 2 contains Potassium Hydroxide. Many people in the industry are strong believers in two step washing. 1 drum of either makes 4.
