To clean them, I use the hottest water I can get, no soap, and a wash rag. If it requires more than that, I use Goop hand cleaner (without pumice).

For protectant, I use Auto Armor (no silicone).

You can always prep for paint/dye, even if you've used Armor All before. You will prep for paint/dye if you're doing it right anyway and odds are that Armor All was used at least a few times back in the 80's-90's on your truck even if you don't.
