Oil oily stains (especially large ones) on paving slabs or concrete walkways look very ugly.
In this review, the author shares an effective way to remove oil stains from the surface of paving slabs and concrete.
In general, oil stains are very easy to remove with a sandblasting machine. However, not everyone has such an aggregate. Therefore, you can try an alternative method.
Stain removal technology
To get rid of small oil stains on concrete and paving slabs, the author recommends using a gas spray with a burner. A blowtorch is also suitable.
If the spot is large, then for these purposes, "heavy artillery" in the form of a propane cylinder and a roofing or homemade burner will be required.
The first step is to heat the stain with a gas burner until all the oil has burned out. We do the same in the event that you need to remove a greasy stain from the brake fluid.
After that, the remaining trace of the spot is removed using a grinder with a cord brush. And the paving slabs look like brand new.
In that case, if the stain is fresh, then you can do without mechanical cleaning with a grinder. It’s enough just to warm it well with a burner.
In this way, you can get rid of any stain, since paving slabs and concrete practically do not absorb oil.
