Even a steam cleaner wont clean it....

I've got an extra console lid if you get desperate enough to switch that out. If nothing else, you might cautiously try some 0000 steel wool.

Try Simple Green and a toothbrush. That should get it and if it doesn't then it probably ain't coming out.

Same problem here. All over the passenger side window sill. Haven't had a chance to put significant effort into getting it out yet though

The guy at The Auto Spa in Plymouth, NH said try peanut butter the natural creamy kind. The natural oils in it break up the stain and it's slightly abrasive.

I like to use "Tough Stuff" on the hard to get out stains. It is a foam that after letting it work for a few minutes reverts to a liquid penetrating into the surface. Has even removed lithium grease from the areas it should not have gotten into.

x2 on the simple green but be careful. Simple green will remove the color too dependig in the surface its used on, it's very harsh.
Dilute it

Hell yes the Simple Green is awesome but make sure to dilute it if necessary. I use it straight to clean my SS Grill. Gets it clean down to the metal!!!

FWIW Adams all purpose cleaner has seemed similar in effectiveness to Simple Green for me, but less harsh. Still dilute it though.

I would not use anything that could abrade the plastic.

Go buy some Surf City Garage BEYOND BLACK Tire Pro Dressing.
Shake Well,
Apply,
Then, get back to us.
(This stuff even makes the running boards look great)

Mr. Clean dry erase pad. Get it wet then go over it. And no I'm not kidding. Works wonders on vinyl and plastic in boat with stuff on it that no cleaner would get off. Will probably work on your stuff as well without making a mess.
