Hi Jordine keep us updated on how you get on, I'm interested how the ot8 will work on this?
Sure went to the job today to make a start, the first treatment was surprisingly good, did a second treatment but didnt have time to stay till i dried you can still see a shadow but it did look alot better when it was dried after the first treatment so im guessing it will look ok when dry. Going to leave it about 5 days to see if the OT8 keeps working and brings any more to the surface, then go and treat it again, if there's still a visible shadow I will try Resiblock.
After I cleaned the drive the first time I found loads of smaller oil stains about 10/15 of them and I found them alot harder to shift.
