I use two things, Meguiars NXT Trim Shine but only every two car washes, and in between I use Stoners Trim Shine cause its a little less greasy.
Good question. There is not much information on this topic here and here's what I'll say. First, you should vacuum the surfaces, then you can proceed to interior dressing. I wipe the plastic and leather with a microfiber cloth, then use a good plastic protector and leather conditioner, mostly a good all purpose product like Fortador Leather Vinyl Trim or The Chemical Guys SPI220. There is an interesting blog on this topic Best car interior dressing | Interior dressing for auto detailing which has a lot of information on car interior dressing, interior cleaning and car exterior. Recommend.what do you guys use to clean the interior? the vinyl and plastic on the dashbord and center console? there is a little bit of something on my center console. looks like some factory goo. not a lot, but i'd like to get it off. anybody recomend anything?
