Pollution - Filthy Engine bays and door jambs

[Chris_DBS]

One of my trade clients is a car dealer that imports cars from Japan of various descriptions and ages, my biggest problem is removing / cleaning the pollution that is in the door jambs and engine bays and basically any tight spot.



I have tried chemical cleaners and abrasive polishes and although these work there are many parts that a hand, brush or any other crevice tool just wont fit. Removing the pollution from these parts would lift the cars to that next level. Obviously I dont want to spend the time removing parts to clean around.



Does anyone know of a chemical/product preferably spray on and perhaps high pressure wash off.



Below are some before and after pics but believe me up close the afters are still well below what I normally call acceptable. And it took over 2 hours to get to this point, Too long for low paying dealers, I'm after something quick and effective.



Does any one have experience with this type of "GRIME"



Any help would be apprieciated

Have you tried a commercial steamer yet?

I, too, wonder about the same thing.





The harsh degreasers tend to etch the paint around the area cleaning.





Using heat as a catalyst is always a helper (i.e. a warm engine), but for grime of that level, I question what can safely be used in a timely manner.
