What are some good "SAFE" cleaners degreasers to spray on and wash off 2005 Jeep Rubi Unlimited 6cyl. engine, that will not screw up anything?
And Simple Green does OK. I haven't been very impressed with its ability to clean up a motor.Simple Green can cause corrosion on aluminum. They do make a version that is not that I believe is actually purple. Read the label to get the correct one if you intend to use it around aluminum.
I keep my vehicles pretty clean, so they do not require a lot of scrubbing. I generally spray it on, heavily, and let it sit 3-5 minutes and hose it off making sure not to hit anything electrical too hard with the spray.
