However, expensive cat litter contains perfumes and tends to clump up and thus, is not helpful in removing the oil. The trick in removing oil stains from driveways is to use inexpensive cat litter.
If the oil stain is very recent or light, pour the cat litter on it and allow it to sit on the stain for around 15 to 20 minutes. However, if there is a lot of wet oil or if the oil stain is very large, let the cat litter sit on the oil overnight. Then, sweep up the litter. If the stain is still moist, repeat the entire process. However, you must take care not to reuse this cat litter and throw it away.

Spray the detergent directly on the oil stain or work the detergent into it. Wash the area with regular detergent and rinse with clean water. If the stain remains, repeat the process.
