Just bought this Accord (91 SE) and here and there is wax on the trim.

Know anything good that will take it off?

Mother's makes a product called "bacl to black". That will remove and restore the black in your trim. Try Auto Zone!

i used silicone spray and it took it off this weekend.. anyone else try it? any long term problems?

Get some all-purpose cleaner and a paint brush. Put tape around the metal part of the brush where all the bristles are(so it doesn't scratch anything). And then spray some on and brush away...this is what I use when detailing at work. FYI, there is a detailing section of AF with some very knoweldgable people. It is in the 'cars in general' section of the forum.
