I typically dust with a microfiber towel, no chemicals. If I use anything, it's 303 Protectant. The upper portion of mine was sticky when I was dusting it last. So I tested P&S Xpress Interior to clean it. Sprayed the dash, cleaned with microfiber, and a good bit of residue was present on the towel. After cleaning, the stickiness was gone and the dash looks great.
This was my first time using their interior cleaner. Did a really nice job and left everything clean, not sticky, not shiny. Just clean. Picked it up from Obsessed Garage based on Matt's recommendation.
