Purple power is great stuff, I owned a detail shop here in my
hometown a few years ago and we used it. You can dilute it
in a spray bottle 1/2 purple power,and 1/2 water,works just as
good as full strength and saves on product usage. The way we
did engines was put a plastic bag over distributor cap and use
a pressure washer ( not too much psi, just about what a car wash has.) after the cleaner has set for just a few moments , just use short quick 2 second bursts with the water until its clean. Then take an air hose if available to blow off excess water.Next start car and let it run for a few moments to help dry it out ( we generally did 3-5 mins. ). After engine has cooled back off you can spray it with Formula 2001 or Armor all . Let that soak in and you should have a clean shiny engine bay. Don't forget to take a rag and wipe off any excess dressing or spots that might have missed while washing. Hope this helps
