I've been using Chemical Guys' Inner Clean + Silk Shine Dressing with a microfiber cloth for the plastic pieces, and their Nonsense APC with a horse hair brush for the cloth. Then I finish off with Fabric Guard for the cloth and their New Car Smell Odor Neutralizer.
I got a generic brand of this today: https://www.amazon.com/California-Car-Duster-62424-Kit/dp/B002TPRNFE/ and it got the dust off the dash and stuff pretty well. The California brand is overprices though, look for well reviewed other brands. That being said I look forward to other people comments as the dusters are just a start for cleaning the interior.
