My riot is an 08 and travels our dirt road about 6 times a day. The dashboard under the windshield collects every dirt and dust particle that comes in. I've Armor-Alled and Windexed to no avail. The dust is quickly attracted. Are there any cleaners that deter settling dust or something easier to use than scrubbing at the dash?
I second both opinions, clean it with a damp rag, then use the meguiars stuff. Also, if yours didn't come with a cabin air filter, check into that. It will help keep the dust out.
I use Lucas Oil Interior Detailer. Doesnt attract the dust like ArmorAll, and has a pleasant, clean scent. (Not that I put much stock in such trivialities, but the ladies seem to prefer clean and pleasant to fish slime and wet dog for some reason...)
