- Apply a liberal amount of fresh clay-based cat litter to the oil stain. Cover the stain well enough so you can't see any oil through the litter. Press down on the cat litter in order to fill any cracks between the block paving stones. Leave the cat litter in place for 30 minutes while it soaks up most of the oil.
- Mix the cat litter with a push broom. This will bring the clean litter to the bottom of the pile just in case there is still any oil left that can be soaked up by the clay-based material. Wait another 30 minutes, then sweep up and dispose of the cat litter.
- Soak up remaining remnants of oil on the surface of the block paving with an old, dry rag. Press the rag onto the surface of the paving and into the gaps. Don't rub the oil stain as it will make it harder to remove. Throw out the rag.
- Pour grease-cutting detergent into a bucket. Look at the directions on the bottle and add hot water as instructed. Dip a scrub brush into the bucket to get it moist with the detergent and water mixture. Scrub at the stain on the block paving. Focus your attention on both the surface of the paving as well as the spaces between the blocks. Rinse the scrub brush in the bucket periodically.
- Rinse off the surface of the paving with a bucket of hot water to see your progress. If there is still an oil stain, keep scrubbing with the scrub brush and detergent mixture until satisfied with the result.
