Best way to clean organic stains on concrete driveway

We recently had some landscape work done in our backyard and the crew used our driveway to store their materials such as pavers on pallets and loads of dirt and rock that they placed on plywood. So for about 6 weeks the material sat on and driveway and they just finished, removing all of the pallets and plywood which had a lot of staining beneath it. I tried power washing with my 3000psi machine and there is still quite a bit of stain remaining.

is there a product I can apply to the driveway that will removing the staining?

What is the driveway..... concrete, asphalt, pavers ?
Organic stains would be from dirt..... not grease or oil. Is that correct ?

Itís concrete and I believe the staining is some from the dirt that with wind and rain collected under everything. Itís not oil.

I'd start with detergent/bleach and a pressure washer [wide tip] Stubborn areas may need to be scrubbed with an old broom.

If the pressure washer didn't clean nothing else will!

If it's cleaning and just the shear volume that is a problem get a plate cleaner!
