Get some Black Wow, or Black Magic it will spruce up the trim, it will also remove the stain.

I had the same issue with mine. Nice to know a little more about it. Thanks for the info!

I live in Pensacola (where today it is 98 degrees) and I've had it at the bonnet hinges and leaking down the front bumper from the bonnet. Called the dealer in Jacksonville and they said to use a non-amonia based adhesive remover. Went to the local auto parts store and of course they had not clue. I'll try the simple green. Thanks.

Yes im taking mine back to dealership this week . Now if i toggle my window down it goes up and down and stays down . Stuff still oozing out under the bonnet . I guees it time to see the dealer to fix things ! It rattles in drivers side door bad also ! I guess its time to fix things !

The guy who cleans my car said he could try and get the excess cosmoline off from under my hood. I called my MINI dealer and asked about this, and they said I shouldn't remove it. I should just continue to spot clean as necessary until it stops running.

I went to dealership yesterday and they replace the wheel arches on both sides of my Just a cooper because it discolored my arches . They changed some part on my window and reprogramed my window ? Total time at dealership 10 hours ! 2 hour drive there and back = Long day ! My dealership service department is not that great not enough workers to handel all the needs of Mini owners . Hope the cosmoline is off or i guess i get new arches in a few months again !
