answer:Dump a lot of baking soda on the spot, add a tiny amount of water enough to make a paste (don’t add too much because you’re using it like a scouring powder). Work away at it with a toothbrush. When you’ve gotten as much as you can this way, rinse well and let dry. If you still have the spot, try using a degreaser such as Zep. It really works, but I’m sure it’s toxic, and I hate to use more of that stuff than I need, which is why I suggested the baking soda first. After you get it all up, you could consider using a sealer on your bricks. Grease and other stains will come up faster.
