Why won the chemicals from retail stores work at removing stubborn oil stains?
We use professional grade chemicals, which are environmentally friendly to treat stubborn stains. A skilled professional knows, which chemical to use, how best to adjust the mixing ratio and finally how to safely apply it to achieve the best cleaning outcome. We always perform spot testing before committing to using a chemical, which may or may not produce desirable results. The retail store brand cleaners will SIMPLY not produce the same results. Our commercial grade cleaners together with hot water application will remove most oil stains from driveways. Unfortunately, a dull stain residue will remain due to the porous nature of concrete. Property owners who rely on the use of “bleach” to clean concrete are running the risk of removing the top coat, which is sometimes referred to as the “cream”. Chlorine when mixed with water forms HCL (hydrochloric acid).
