I've used a product called Gunk, it is a degreaser. Warm up the engine, spray it on and leave it for ten minutes or so, then spray it off with a low pressure spray. Avoid direct spray with electrical components to be safe. <br>You'll find it leaves a rainbow trail in the water that runs down your driveway, not sure how good it is for the environment!?<br>But, it does a hell of a good job cutting build up crud on the engine. After I take a brush and rag and wipe down the stuff that doesn't spray off and give it a once over agian with the hose. Just use it on the metal parts and use a vinyl/plastic or general cleaner on all the plastic stuff.<br>Should look good! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">
I use Simple Green, its a darn good all natural degreaser. This and citrus based cleaners seem to work the best in my experience, and they wont kill the grass or any small children. I tried doing this without running the engine, dont do that, Im not 100% sure what happened, but the car would start and stall and start and stall, the Check Engine light came on, and it took well over 24 hours before the car was running ok again. I assume I got watter in places it shouldnt be. What I was told to do next time, and is what I do, is do this with the Engine running, that I wont have the problem then. I first rinse the engine with water, while its running, then I spray the entire area with the degreaser, then I scrub with a brush, then I rinse. Sometimes I will repeat if necassary. I hope this helps.
