Powerwashing alone does not take the red dirt stains out. Why are red clay stains so hard to clean from concrete and masonry? Possibly because what gives the reddish color of the dirt is iron oxide or better known as rust, which is highly insoluble in water. In fact, iron oxides are often used as inexpensive earth tone pigments in coatings, paints and colored concrete. The process to remove red dirt stains is a chemical (cleaner) and mechanical (power wash) combination. An acidic based cleaner is more powerful because it will bubble up the red clay that is deeply imbedded in the concrete. Yet, one has to be careful as not all acid cleaners are equal. Straight acids (or highly concentrated) may be too powerful and actually burn or harshly etch the concrete. If an acid cleaner is diluted too much, then its not going to break the bond the iron oxide has made to the masonry or concrete. Our balanced Red Clay Stain Remover is buffered with water and surfactants to only micro etch the concrete, thus removing the red clay but not adversely affecting the surface.
