The first cleaner is PaverCleen Concrete Degreaser. Paver Clean as the name sounds does clean pavers and all pavement. This cleaner, when diluted with warm water, will provide an economical high performance cleaner. Grease, oil and dirt are effectively removed from masonry and concrete surfaces. A variety of additional surfaces such as bugs, mold and other biological growths will be removed from steel, glass, and plastic. Make sure to test all surfaces in an inconspicuous place prior to full application.

Another degreaser is ZEP citrus cleaner. This cleaner does a great job but the citrus scent can be rather intense. On average this cleaner tends to be 87% more expensive.
Poultice Kitty Litter
There are different ways to deal with the oil stains.The first and most basic method of cleanup is known as a poultice. Poultice is created by saturating an absorptive material like kitty litter or sawdust with an intense solvent like acetone or MEK (methyl ethyl ketone). Osmosis will slowly remove the oil from the concrete.
If the oil stain is new, the kitty litter will soak up the excess oil and contain the mess. Once fully absorbed you can brush away the oil kitty litter. This technique is expensive and requires numerous applications. It is better for controlling the mess of a recent spill, not removing it. The stain will likely remain on your concrete after the kitty litter is brushed away and will require another cleaner.
Liquid Dish Soap
Liquid dish soap and water is a common household solution. Soap and water are lathered onto the stain. This method requires many treatments and intense scrubbing. Much of the oil stain will remain deep in the pores of the concrete for years to come.
Made up of single-celled microorganisms, this little cleaners love oil. They feed on oil as the enzymles and oxygen inside them break away the oil stain and convert it to carbon dioxide. This is a great method for cleaning up disaster zones such as in the Gulf of Mexico. Cleaning a driveway is too small of an application for microbial cleaners.
Many cleaners have an intense odor. Make sure to test the product outside before using in a garage. The Zep and Pavercleen were powerful but could be used inside. The UGL cleaner was almost impossible to use inside. A mask was required. No matter what cleaner you use make sure to have protective gloves and goggles on.
5 to 1 Ratio
Many of the cleaners can be diluted. The zep says it can be diluted up to a 16 to 1 ratio while the pavercleen states it can be diluted up to a 5 to 1 ratio. An added benefit is you can save on shipping by ordering a concentrate and dilute it with warm water on the clean up site.
