Best way to get rid of cosmoline

The underside of my engine is coated in thick cosmoline. I originally thought it offered some sort of protection and should leave it. However, when it softens from heating, sand and grit adhere to it... it looks like fried chicken.

Citrus degrease?, Engine cleaner??
 
I had the same thing on my car plus 25,000 of road grime. I used EF Engine Degreaser, which cut through the cosmoline. It was necessary to agitate with a scrub brush. The solvent in EFED is delimonine (sp?), which is quite strong, but not as harsh on rubber and plastic as petroleum solvents. If I had to use a petrol solvent, I'd use turpentine.



You will need to replace the cosmoline with another protectant. I've been using Meguiar's Engine Kote, which seems to be working pretty well. Apply 2-3 coats on the bottom.

David,



Did you mention before about using brake parts cleaner to remove Cosmoline????



I was wondering if this would be too harsh...
 
If it is true cosmoline, then you'll need something like Disel fuel to take it off.



It probably isn't so using a degreaser should probably help. If not, then you'll need some sort of solvent.
 
It's pretty thick stuff, and I've never heard it referred to by anything other then cosmoline when people talk about the Porsche underbody.

No, I would not bring that kind of solvent anywhere near my P-Car.





pcar996TT... Yes, it is cosmoline that Porsche sprays under the cars. Cosmoline is a very heavy petrol-based wax. Kerosene or other slow flash fuels will remove it, but they make a mess and smell pretty bad. Delimonine cuts it very fast.



Meguiar's Engine Kote is a non-permanent coating made for protecting engines after detailing. It replaces the wax coating applied by all manufactures. It dries clean and tack free. You should use it on your engine and in your wheel wells twice a year. Use it more frequently if you live near the ocean or drive in salt conditions.
 
After 2 cans of EF engine de-greaser , 1/2 gallon of turpentine and two toothbrushes, I finally removed the cosmoline and attached dirt from the suspension and undercarriage. The car has 4200 miles on it, and I think half of Virginia stuck to the bottom of it.

BTW, I really like the Meguire's Engine Kote, gives a nice finish. It smells like Johnson's liquid floor wax...

Excellent job... very, very nice! Yes, the Meg EngineKot has a unique smell. Best of all, it does not create fumes when the engine come us to temp.
