I use a pump sprayer with hotwater and apc cleaner added. I spray everthing down. Let it sit for a little while. In the south a little while is 10-15 mins.:glasses:I'll then get some small bushes and some rags and go to town wiping everything down. Then I wash everything off with fresh hotwater and then dry with compressed air. But I will tell you this, it is easier to keep the engine clean than it is to clean it. I hope this helps, also for the new look VRT is the next best thing to the In & Out spray.
