I recently picked up some asphalt oil on my motorcycle commuting back and forth to work over freshly paved streets. The heat just baked it onto the cases. I tried Goo-Off, brake cleaner and carb cleaner; nothing worked well and all leaving most of the oil stain behind. I picked up some GreaseGo from Let It Ride out of desperation in trying to avoid anything abrasive on my antique motorcycle. First try with GreaseGo just melted the stains off the engine cases. I'm impressed!
Thanks for considering the environment when formulating your product. It has now found itself on shelves in my garage and home.
