Well you know there is no product on the market today that I am aware of that you can spray on or brush on and wipe oil of a concrete because it is down in the concrete. You got to take it out. This is what you will do, call your local building supply store and pick up a degreasing solution. There are all kinds of them out. There they are normally detergent that will state on the label degreasing solution. Now if it is a powder or a liquid mix it up and put it on a low prayed sprayer one that you can control because you do not want to brush this own to the area were the oil is. You want to spray it on.
So what I have done I have taken a piece of plywood here now to simulate an oil stain. I just take felt tip and I will spread it over the surface. Now if you do after you mix up the degreasing solutions spray it on spray it all over good and wet because you wanted good and wet. You want it do fill go down deep in to the concrete. When taking old prey towel? One of which well you are not going to use anymore. And to lay that over top of that wet area. N
Now it is normally better to wash the entire carport before you do that beacaseu that is way at least it is all wet at that time then you can spray the degrease solution and that on with the terry towel. Now again wet it down on the top of the terry towel because you want that nice and wet because what you are doing you are producing a posses. You want that wet you want that to go down deep and you know what happened to water when it comes in contact with solvent or oil or any petroleum product, it will float to the top. So up it comes and the towel is there to pick it up. And now happens if it I a warm day? Well a warm day, we do not want it to evaporate so we put it over top a piece of plastic. Put that piece of plastic over top and that is going to retain that moist. It is not going to allow it to evaporate. And do not forget always wear safety goggles and rubber gloves when working with the greasing solutions, but after that 5 hours you can take a pick every. Now and again see how things are coming you might want to wet down the towel a little bit more, but after 3 to 5 hours you very simply take the plastic back take the towel back pick your host and host it down and it is gone.
