Remove oil stains from concrete with this cleaner
Cortec
This company’s MCI line focuses on corrosion protection for reinforced concrete, and also includes several specialty products that provide excellent companions for concrete or construction site maintenance. One of these is MCI-2061, a powerful cleaner (photo) that safely and effectively cleans oil stains on concrete using “green” chemistry. It is said to be an excellent and effective alternative to harsh caustic or acidic cleaners. Initial cleaning is due to biodegradable surfactants in the product. Ongoing cleaning action is performed by microorganisms that activate when applied to pre-wetted concrete and rinsed according to instructions. These microorganisms are specially selected for their ability to biodegrade hydrocarbons, such as those found in oil, diesel and other materials that stain concrete. Spores that remain after rinsing germinate and continue to eat away at the residual hydrocarbons not removed in the initial cleaning process. MCI-2061 microorganisms carried away with the rinse water can also work to clean up hydrocarbons downstream in drains and sewers. — Cortec Corp., St. Paul, Minn.
