I have tried a pressure washer with special concrete concentrate, straight bleach and even KLR but nothing seems to take it off? Any other suggestions?

How to Remove Rust Stains from a Driveway
Iron can leave rust marks on your concrete drive that may seem impossible to remove. Here are some methods to use for removing those unsightly red stains.
Steps:
1. Mix 1 ounce of tri-sodium phosphate (TSP) in a gallon of hot water. This chemical can be found at hardware and paint stores. Wet the concrete and use a scrub brush to apply the solution. Scrub vigorously and let the solution soak into the concrete for 10 to 15 minutes. Rinse well.
2. Try a product called Iron Out, which is sold in plumbing supply stores.
3. Combat really bad stains with a pressure washer and muriatic acid. Apply the acid as directed by the manufacturer, leave it to soak for a few seconds, and follow with a pressure washer set at 2,500-3,000 psi. Sprinkle baking soda over the cleaned area to neutralize the acid and wash again.

Hydrochloric acid, HCl which can be purchased as Muriatic Acid at any hardware store. Wash the driveway down with a hose first and let it dry. Make sure there is NO bleach around - they form chlorine gas when combined!! Test a small area first it may discolour the pavement and you don't want to have a funny shaped spot on your driveway. Straight CLR, if left to sit should work, but if you tried that with no luck, try this.
Cheers.

Try Rustblast by KBS coatings. Keep stain wet with Rustblast (comes in spray bottle) for about 20-30 minutes then hose off. Can be used on a variety of surfaces including concrete.

Yeah, then it becomes a yearly chore but it will help to keep it from oil stains from the car. If it is "in the cement" painting the cement is the only thing you can do(and that does not work for long before the paint peels off)

Muratic acid will do the job, be careful with it use gloves and do not breath.
