Organic Vs Non-Organic Staining Removal

Organic Growth vs. Non-Organic Staining


All stains are not alike and all materials that can show ugly stains on your home or commercial property vary as well. These stains can be categorized into two types: organic growth and non-organic staining. Both are unsightly and both reduce not only your property curb appeal, but value as well. They both also need to be dealt with as soon as possible they each lead to additional damage requiring expensive repair and replacement later. 


Facts About Organic Growth 


  • Mildew and Black Fungus –  This is some of the worst growth problems for a homeowner. It typically grows on siding, which can result in black stains that are difficult to remove. Mildew is often blamed for these stains but frequently, in the southern humidity, the culprit is black fungus.  


  • Mold, Algae, and Lichens – Other growth such as mold, lichens, and algae have varying behaviors dependent on sun or lack of sun. They often grow on wood, roofing, and even brick and stone.


  • Damage Done and Treatment These kinds of organic growth will feed on the natural materials they grow on. Asphalt and non-petroleum roofing materials such as limestone or fiberglass can also suffer organic growth damage this way. Using hot water or various chemicals with power washing or soft washing can be effective, but care must be taken to select the proper treatment in order to avoid further damaging the natural materials being cleaned. 


Facts About Non-Organic Stains 


  • Stains on Concrete and Other Hard Surfaces – Petroleum products are often the primary source of non-organic stains on hard floor and pavement surfaces. As dirt accumulates, petroleum products, spilled household paints, and other chemicals can be very difficult to scrub out, especially over time.   


  • Damage Done and Treatment Skid marks, oil, engine fluids, and even dirt can accumulate and eventually break down concrete, asphalt, stone, and tile. A good pressure washing can eliminate most any stain on concrete but needs to be assessed and handled properly to avoid spreading petroleum products with water run-off into the surrounding environment. Use of pre-treatment or special cleaners might be used to help avoid the excess run-off with a final power-washing.
