Step four: a WATER BASED dressing lightly misted then wiped down if possible
ArmorAll--a much maligned company--the original (but not the original name!) and still the world's leader in dressings and the one most others still try to emulate. The latest version (since at least 2005)
ArmorAll Protectant is a water-based dressing (PDMS), the formula changed due to VOC regulations and meeting OEM requirements.
Not saying there aren't better water-based (PDMS) dressings out there--there probably are; but
ArmorAll Protectant set the standard. This is also saying that there are probably other products from ArmorAll that do not meet this criteria.
