/diy/ - Do It Yourself

I'm not sure if this is the right forum to be posting this, but I'm in desperate need of some help with cleaning motor oil stains and also power steering stains from concrete. I am going to be moving within the next week and I would really like to try to get all/most of my deposit back, so I'm hoping to be able to do a good job of cleaning up the stains that my 2 vehicles have left on the concrete out back of my apartment over the last two years.

I have already searched Google for ideas and there seem to be some good ones, but I was hoping to get some specific suggestions for both motor oil and power steering fluid.

Also, does anyone know if I will likely need or benefit from renting a power washer? Or will I probably just need to use some sort of concrete cleaning solutions and a scrub brush and my garden hose?

Any and all helpful replies will be genuinely appreciated!
