Zep purple with a heated ultrasonic cleaner is my first step for greasy parts. Then I hit them with a glass bead blaster. Note: Zep purple reacts with Aluminum parts! You have to be careful how long they stay in there. In theory, it could eat the aluminum until nothing is left.
For painted parts, I use "Strip-it-dry" paint remover. One of the few that REALLY work. Others have had the good stuff removed and are basically useless.
But there is no silver bullet. What you use depends on the part design, its material make up and if its greasy or just just dirty.
