What removes oil and black undercoating but not paint? Options

[mskala]

My car used to leak oil from lots of places. After rebuild, now everything's pretty
good. But, particularly from under the oil tank area, oil has got on a large area
under the floor and longs.

I found accidentally that the CRC Electronic Cleaner doesn't seem to remove paint,
but it is so weak that the black undercoat (wurth?) turns into a huge amount of black
goo that hasn't really come off the car.

I want to save any paint and the white-ish undercoat. Any products that will do this?
I assume my paint is the old lacquer type paint.


Thanks

I use BrakeKleen (the one not sold in CA) and it cleans stuff off easily without hurting or dulling the paint. I never would have guessed it but my buddy Greg has been using that on his cars for years w/no issues on any painted surfaces. As always, if you try this, try it on a spot that you can risk it on.

When we installed my rear glass, we used urethane - what a mess that was because we cut the tip of the tube off so the hole was too big. (IMG:style_emoticons/default/wacko.gif) But it all cleaned up nicely using BrakeKleen on microfiber towels. (IMG:style_emoticons/default/smile.gif)
