Grinding kitty litter into the surface can also draw out grease and oil

Why?
Because the OP's liability IF someones kid has a reaction while playing in the area, dog eating grass, etc. if far more impacting than the need to clean a patio, that may not be his responsibility.

BTW: Kitty litter will work on fresh petroleum spills and not on aged stains. Without use of some chemical for removal.

And don't breath that shit in, it sucks.

Edit: After I've done what I needed done I neutralize it with water and baking soda.

Maybe try some CLR. Seems to look like it might work on something like that according to thier advertisements.

The strength of the acids used in modern over the counter acids are not that bad. I'm sure the sky won't fall if you follow the directions.

Thanks for your concern. It IS my responibility since I made the stains. I'm not worried about liability as I can control access to the area from kids, pets, etc. The apartment will not do anything until I move which is still ten months away and then, they just pressure wash it, which did not work. I have a bit of an OCD/cleanliness personality and I've been really stressed recently... so hardcore cleaning is a way to let off some of the pressure, but this stupid patio just won't work with me, HA! I think it would be awesome to smooth out the patio, acid wash it, then stain it a darker neutral color, but I don't think management would go for that! HA.

Try this Bear-dampen the areas with a very light spritz of water. Sprinkle some Tide POWDER laundry soap on the area and scrub it with a stiff bristle brush. Let it set for a couple of hours then rinse.
Always worked well in a shop environment.
Keeping sawdust on the areas will pull old oil stains out as well.

For grease and oil use brake clean. Works great.

Brake clean and a green scratch pad for hard stuff.
