Center console buttons.
Oh I didn't realize those got sticky too. I just cleaned mine with glass cleaner, no sign of problem with them yet.
This is a very helpful thread for those of us who may have to tackle this one day. Nice job guys. The interior looks fantastic!!
I used a piece of old credit card as a scraper, a toothbrush, and a small plastic dish of Greased lightning to do most of my interior in place. Windshield vents and vent dial recesses are all that's left. I was glad I didn't risk breaking them on removal. The card does not mar the plastic and I just followed up with Armorall treatment. Everything looks great, especially the center console. Tons of paper towels.
