Nice engine bay Kean! I think I will use the hose for the first scrub down to get the major stuff off, then go through it with the simple green and some clothes.
When I went to look at the car, I was in fact hoping that it wasn't cleaned prior. Cleaning can be either a sign of being meticulous or trying to hide something, but one always needs more than just inferences.
Cosmetically, the car has some door dings, bumper scratches, and things of that nature, but for the deal I got those things are easily fixable. Mechanically it's in fine shape; the previous owner wasn't a meticulous cleaner, but he had a notebook full of service receipts done every 3K miles.
