Be careful with Armorall and similar products. They can contain plasticizers which create the high gloss on surfaces. Over time the plasticizers take the place of certain chemicals in your dash plastic etc. If you stop using them, the surface dries out and cracks.
I've been using Meguiar's Protectant and/or 303 Aerospace Protectant on most surfaces. I use Detailers Pro Plexall Plastic Cleaner for clear plastics. I only do this once or twice a month and just keep up with light dusting and vacuuming. Also, be very careful when cleaning the gauge cluster plastic and/ or the clock/info display. Use microfiber or t-shirts that are very soft. Any scratches can make the displays almost unreadable in sunlight. I've seen this happen in a friend's F-150.
