Don't get that Purple Power on your driveway unless it is cement. Purple Power will eat most anything made from petroleum product including asphalt, blacktop, grease, etc.

It is very hard to dilute and it will eat the binder from between the little chunks of gravel while you rinse it from your driveway.

It is very effective at cutting grease, but I am not sure how good it is for your parts. It would take a lot of water to rinse them to ensure all of the Purple Power is gone so it does not kill whatever lube you apply.
