Have you seen concrete parking lots ridden with oil stains from cars and other vehicles? While some businesses write off this issue, many others are looking for a solution to this issue. When oil is stained into concrete, it can produce an undesirable appearance. Fortunately, there are a few common solutions to remedy this issue.
Sometimes all it takes to remove an oil stain is a strong detergent, scrub brush and a sponge. However, this method typically only works for smaller and newer oil stains. For larger and older stains, use a concrete cleaner or degreaser. These products are concentrated alkaline soap used to scrub out oil from a concrete surface, and loosen up the oil stain to allow for a simple removal process.
Commercial concrete cleaners have one downside. They have a harder time working properly for heavily contaminated stains. If your oil and grease stains are years upon years old, another method will work more effectively for your purposes.
Poultice is a solution made by saturating an absorptive material with a strong solvent. Common options for absorptive materials include:
- Kitty Litter
- Pool filters
Once your material is chosen, combine with one of the following solvent options:
- Lacquer Thinner
After combining, smear the result over your oil or grease stain. Next, cover the poultice and stain with plastic, and watch it do its trick! The process of osmosis will take over, break down the oil stain and the kitty litter or saw dust will absorb the oil. While effective, the only downside to this method is the cost and time it takes. If you’re patient and have a budget, this option will work well for you.
Another option is actually a recent stain removal advancement; special single-celled microorganisms that survive on crude oil are actually used to remove a stain from concrete. The microorganisms eat up the oil, digest it and turn it into CO2. When the oil is no longer available, the organisms die and the concrete is completely clean!
