Hey,
Did hear that coca cola was good?? havent tried it yet. also fairly liquid and swarfega maybe then scrub it hard and if you have one pressure wash it off.
Depends on the patio is it block paved or slabs etc, just turn them over if you can.
hi,
if you put some water soluble oil on top of the oil stains and add a little water and mix the lot together with a brush until it goes a nice creamy colour. you'll be able to just rinse it all away with clean water from a hose.
