How do you remove oil stains from pavers?

I know for sure that putting clay cat litter on the pavers will absorb a lot of the oil, but you will still have stains on them. I think that muratic acid might get the rest of it up. I know my grandparents use to use it to clean the floors of the garage. Keep this in mind though. Muratic acid 'etches' surface of concrete. If you put the muratic acid on some of the pavers, but not all of them, it might change the intensity of color of those pavers. I don't know this for sure though.

I considered acid but was afraid that it might harm my dog. I found a new green product called Oil Gone Easy S-200 which eliminated my stain in about a week without the use of toxic chemicals. Very good results.

THIS WORKS A TREAT!

I have porous brick pavers which were badly stained with oil from the car. Mix Sodium Bicarbonate (common bi-carb of soda) with a good splotch of dishwashing detergent (I used Earth Choice, an Australian brand, environmentally friendly from the supermarket) and a small quantity of hot water. After scrubbing it in really well and leaving it maybe 10 minutes to soak in, I rinsed it off with a couple buckets of hot water and it looks GREAT! After having tried engine degreaser with little effect, I'm delighted that this is so environmentally friendly too!
