How do I get a large oil spill out of pavers, with no stain showing.

If it’s a fresher stain, dump a bag of clay cat litter over spot. Let it soak up stain, then sweep up and throw away. Blue Dawn scrubbed into stain may also dissolve the oil. May require a test spot in inconspicuous spot first.

Is it feasible to just turn them over? I'm not sure you will ever be able to completely eliminate the oil stain.

It is very unlikely that you will be to completely.

Grab some cheap auto dishwasher powder, wet down then sprinkle on let it sit overnight I possible at least several hours . Scrub with broom and wash off.

Pour baking soda on the spill and let it sit to absorb the oil. Brush off and then apply undiluted Dawn concentrate; let that sit for 20 minutes, apply hot water, and then spray off with high pressure from your garden hose. If that doesn't work, get some TSP or concrete cleaner at the hardware store and follow directions on the package.

Pour kitty litter on it and leave it set. It will soak up the oil. Then sweep it up. Repeat if necessary.

First I would sprinkle some kitty litter on top to absorb as much as possible, then sweep up after a few days. The go to the Dollar Tree and get a couple bottles of Awesome Degreaser and a scrub brush. Treat the area, let sit and scrub, use old cloth T-shirts to sop up the oil. I like a scrub brush I can screw onto a long handle from the hardware store. Repeat a few times to get as much as possible. Then if there is still a stain, I would pour some mineral spirits on it and scrub with brush, then use a hose with a power nossel and some soap.

PS don't put the rags and paper used to soak up oil in a closed container, put in a paper bag and leave open outside so there is no possibility of spontaneous combustion.
