While I'm sure your method will work just fine Joe, it sounds extremely labor intensive. What about simple high pressure steam cleaning? There are numerous detailing shops in this area that will do a complete undercarriage steam cleaning for about 50 bucks, engine & tranny only for about $25. The results I have seen using this method are great! Most will even include touching up any chassis paint (usually flat black) that has been knocked off by the high pressure steam cleaning. I have had this done to several cars and the result usually is "like new". This method is commonly used by used car dealers to clean up the "top" of the engine so when you pop the hood you see "like new". Most detailing shops do not include undercarriage cleaning (except for wheel wells) in their price of "whole car" detailing, but will usually do it for an additional charge, or will do it without doing the rest of the car. If you prefer to detail your own undercarriage after cleaning I highly recommend high pressure steam cleaning. There is NO resulting residue from various cleaning products and you can begin touch up painting without further preparation. Regards, Ed Thompson (#6419 since 1982) Midlothian, VA USA
