The previous owner of my house would appear to have been carrying out oil changes on the driveway, and the monobloc is somewhat oil-stained.

I've tried to soap/pressure wash it, but it hasn't budged.

Any ideas on removal methods that won't be too harsh on the monobloc?
The wife will kill me if I discolour it with abrasive chemicals......

Scrubbing with a stiff brush, water and brand-x washing up powder worked well for me although this wasnt monoblock. Test on a small area first maybe?

Try scrubbing swarfega hand cleaner onto it and washing it off, might take a few goes but should work.

Depending on the surface area, Swarfega do an actual surface cleaner and degreaser which you can put in your pressure washer, screwfix should stock it, dunno where else.

When I got some old engine oil on concrete some years ago, the method I used to get it off, (after many failed attempts), was to brush in Wickes Paintbrush cleaner, (an EXCELLENT water-soluble degreaser), leave it for 30 minutes, then pressure wash it.

Just cover the whole path in oil so it all looks the same !
