Daox, may he find the Golden Aero, asked what people use and people said kitty litter, Oil-Dri, diesel, and non-chlorinated brake cleaner.
I think that I have tried brake cleaner.
I don't think it did anything.
Then again, soap hasn't seemed to do anything, either.
The Donut Boys tried Tide, Rustoleum, and BacKrete.
The BacKrete didn't seem to do anything, but they said it must be designed for fresh oil spills, so if you apply it immediately it should work like a charm.
The Tide did something, but the guy who used it swore by it saying that his parents didn't let him stop cleaning until the stain was gone.
The Rustoleum worked better, but they still used a pressure washer.
This guy apparently whispered because he fixed his motorcycle at a stranger's house while they were away and he didn't want anyone realizing he was there. He said that Tide doesn't work well because it is designed to break up everything but oil.
He used Cascade dishwashing detergent and it seemed to work perfectly with tons of scrubbing.
I used Cascade dishwashing detergent and my power scrubber and it didn't work well!
