Start it up and go for a drive.
Once home allow engine to cool and than apply CD-2 Engine Detailer.
Follow the simple instructions on the can.
And once you are done you will be happy with the results
I tried the Simply Green today and I was amazed on how well it got rid the grime off the engine. It even smells nice.
