Cleaning concrete

I am wanting to clean unsightly oil and general stains off of my concrete driveway. What is the best way to go about this?

Thanks

John

Do you have a pressure washer @jbodey?

I do but it is very slow and tedious work. It is difficult to get rid of all the stains and the area needed cleaning is about 6 X 18 m

I am wondering if there is a good chemical solution available.

Thanks for the update John (@jbodey)

Do have a look at @Stephen-H's suggestion of Oxalic Acid on this discussion - https://www.workshop.com.au/t5/Interiors/Removing-Stains-From-Concrete/m-p/13662

I would start off with just hot water and detergent and a stiff brush first. That way you don't do any damage to nearby plants or get any chemicals into the stormwater. Good luck @jbodey.

I understand @jbodey. A pressure washer can be a little slow. But it is better than having to scrub on hands and knees!
