Definitely not oil. New drive, been down approx 6 weeks.

Brake dust ? Really ? If it's ground into the surface of the concrete then you're probably not going to be able to remove it without using say a waterblaster and that's NOT recommended on concrete as it'll literally blast away some of the concrete surface !

well logic would tell you brake dust would only really show up like in your description if someone whipped a brake drum off and washed the dust with brake cleaner on to the concrete. My brain cells asked me if You was talking rust stains

This stuff works well getting it off the wheels. Can’t say I have tried it on a concrete drive but should not stain.
What is the driveway made of? -Im thinking good old fashioned hot soapy water a scrubbing brush and soap

I expect that brake dust is a mix of the pad material & the disc/drum material & so it will be made up of a lot of fine rust particals.
CLR product, concrete cleaner or evapo-rust from Supercheap auto

If it's black marks it's probably just rubber off the tyres.
