You can learn how to remove grease from concrete in your driveway or garage in a few simple steps and that too with the use of non-toxic products that you can easily find in the store near your place. Begin by spreading a thick layer of sawdust over the grease so that it can soak up the excess lubricant on the surface. It is best to let the sawdust sit on the concrete for a day or two and then you should brush it away gently using a broom and a dustpan.
Once you have removed all the sawdust from the concrete surface, you need to pour some dry cement over the dried grease stain and allow it to sit for 1-2 days’ time. The cement will absorb the grease stain from the surface and leave it stain free. However, just as you removed sawdust, you should sweep away dry cement as well as hosing it down the sewer will clog the pipes.

You can even use kitty litter instead of sawdust for this purpose and it works equally well when it comes to absorbing excess grease from a concrete surface.
