Can it be done?
Had a pretty major fail at my Nans, which resulted in probably half a litre of 12k old dirty diesel oil on the floor. Which I then made worse and spread it around the garage and driveway with a broom and hose.
Did use washing up liquid and bleach (and god knows what other chemicals Nan mixed into the bucket lol! 
) but is seemed to make no difference.
I was doing car stuff at Nans on the proviso that I didn't make any mess, and had managed to break cars, change gearboxes and remove and refit an engine without making mess, until now.
Anyway, I'm going on...TLDR - what can I use, if anything, to clean oily stains from concrete? I do have a pressure washer if that'll be of any help, but don't think it will be without some sort of chemical....
Cheers
