My neighbour has a Jaguar Type-S and it's been parked up for a good few weeks as it had a leaking radiator, so he asked me to change the radiator for him. When I was checking the car for whilst it was parked on his drive I could see that it had some long term oil leak issue as well. So I go get his car and reverse it onto my ramps look in front and there's drops all over the drive in front of the garage. Thinking it's just coolant I think no further of it and carry on. About half an hour later I take a closer look and realise that's not coolant but oil ! So I have a look under the Jag and find it's leaking auto transmission oil ! So I quickly get out there with paper towels to soak up as much of the oil drops as possible I then get out some Swarfega Patio and Drive cleaning solution. Pour some on, srub it with a harsh brush and jet wash it off. I feel pleased as the Swarfega stuff seemed to be doing a good job of degreasing and breaking up the transmission oil. I concentrate the jet wash stream on the spots where the transmission oil fell. With the area fully wet, I can't see the spots anymore, it seems that my swift action had worked and I had got rid of the marks. That is until I get out there this morning and see that the marks are ALL still there standing out loud and proud ! To say I was fuming is in understand statement ! You try to do someone a favour by helping them and end up doing damage to your own property. Does anyone have any ideas how I can get rid of these frickin marks ?
