Clean with Griots` Interior Cleaner or Nextzett Cockpit Premium, both excellent. Detail With Griot`s Interior Detailer or Herrenfarht Dashboard Detailer but what I have done a few months ago is use Pinnacle Black Label Leather & Vinyl Coating for the entire interior, including seats. I like the low sheen and seems to repel (or at least not attract) dust.
I`ve been using the Pan-approved P&S Interior Xpress Interior Detailer product over the past year. Actually, quite a good product and fairly priced at the gallon size. When I need something really quik, I reach for the HD Total.
I have been using Nextzett Cockpit Premium for years and love it. I will be trying the new Gyeon Interior Detailer because i`m hearing great things about it.
Either the Cockpit Premium or the Meguiar`s stuff. I have the GG version but haven`t tried it yet. Nor have I tried any of the products that my fellow Autopians have sent me
