Griots doesnt actually make any of their own products, most of it is relabeled 3M stuff. All of their products can be found for less money elsewhere.Griots' Best of Show wax for outside.
Vinylex for all the black stuff and plastics.
I use Griot's Clay Bar to prep the paint before waxing. It's very gentle.
I dont know where toyota says that you can spray it out. I think you took "washable interior" to mean that; it doesnt. There are no drain plugs like in a wrangler to drain the water, plus there is a lot of electrical stuff fairly low so you'd have to be a "hose master". I recommend using a wet towel to get the mud and stuff out. If you decide that you HAVE to hose it out, you should keep the water on the floor, and use a shop vac to get the standing water out.can't you just spray the inside out with a house like toyota says?
