Gasoline can be effectively cleaned off of concrete with kitty litter to remove any excess oil still sitting on the surface, as well as a grease-cutting dish detergent to remove the stain. Kitty litter is made with an absorbent clay that soaks up liquids well. Stubborn or old gasoline stains may need more powerful products, such as trisodium phosphate, to completely remove them. You also need a broom, scrub brush, absorbent rags and cleaning gloves.Continue Reading
Pour fresh kitty litter over gasoline still sitting on the surface of the concrete. Use a broom or the shoes on your feet to grind the kitty litter into the oil for maximum absorption. Allow it to sit for a few hours. Sweep up and dispose of the kitty litter in a container suitable for safely throwing away hazardous materials.
Squirt a powerful, grease-cutting dish detergent over any remaining gasoline stains that have soaked into the concrete. Scrub dish detergent into the gasoline stains vigorously with a stiff scrub brush.
Rinse away the detergent with boiling hot water, then blot dry as much as possible with an absorbent terry cloth rag. Repeat scrubbing, rinsing and blotting several times to remove all or as much of the gasoline stains as possible.
Combine an ounce of trisodium phosphate (TSP) with a cup of water and enough powdered talc to make a creamy paste. Spread the mixture over the gasoline stain and let it dry for 24 hours. Scrape up the dried paste after 24 hours with a metal spatula and scrub the area with water and a stiff scrub brush, then rinse off the area. You may need to repeat this process two or three times to completely remove very tough stains. TSP is harmful to the skin -- make sure to wear protective cleaning gloves when you use it.

Because of the porous nature of concrete, the best way to remove stains is by absorbing the stain from the concrete material using trisodium phosphate for oil and grease or paint stripper for paint. Rust stains can also be removed, but requires that the surface layer of concrete be dissolved.Full Answer >
One of the most common ways to remove an oil stain out of a granite countertop is to clean the surface, make a cleansing poultice, apply it to the stain, remove it after 2 days and rinse it off. The surface of granite is a bit more porous than most other stones, which means that liquids such as water and oil can penetrate it. Oil that leaches into granite leaves a stain on the surface, which can be difficult to clean off.Full Answer >
