PetroClean is a concentrated combination of oil-digesting microbes and a small amount of surfactant that is diluted with fresh, clean water before use, and can be used in a variety of ways. PetroClean has been used to remediate contamination from gasoline, diesel, and heating oil tank ruptures (see PetroClean Success Stories here), and has been authorized for use by the Virginia Department of Environmental Quality. PetroClean is also an effective parts/contaminated surface cleaner, and can be used in combination with oil-absorbing materials like kitty litter to pull oil stains out of concrete.
PetroClean’s surfactant action helps break up non-chlorinated petroleum hydrocarbons, forming oil micelles suspended in the water used to dilute the PetroClean concentrate or in groundwater when used to remediate underground spills. The oil micelles have a large surface area, which enables the oil-digesting microbes in PetroClean to more efficiently and quickly digest the oil. The oil is broken down into carbon dioxide and water, and once the food source (petroleum) is gone, the microbes die off.
PetroClean is normally diluted between 1:5 and 1:20 in water. Heavier petroleum hydrocarbons like grease or crude oil on surfaces like concrete typically require a less dilute solution of PetroClean and lighter hydrocarbons like gasoline or diesel allow the use of a more dilute solution.
Most surfactant and oil-digesting microbe products are sold separately, and are injected sequentially. PetroClean is the only combined product on the market, and because it is so concentrated, it is typically more cost-effective to use than competitor systems.
