How do you remove oil stains from concrete?

[#1]

To remove oil stains from concrete, you can use CLR 750ml Grease & Oil Remover alongside a Sabco Bamboo All Purpose Heavy Duty Scrub.

Unfortunately, if the oil has baked into the concrete, this technique may not prove 100% effective, and it might be very difficult to remove the stain completely without grinding back the concrete.

Grinding back the concrete involves using a concrete grinder to mechanically remove the top layer of the surface, which can help eliminate deeper stains. Bunnings offers concrete grinders for hire.

If you try the degreaser and scrubbing brush and find that you are not happy with the result, you could also consider concrete paint as an option to cover up the stain. Note that you would need to paint the entire area for uniformity.
