Just do a small section of seats at a time with Scrubbing Bubbles. I like to scrub first with semi-soft brush first and then wipe away with cotton cloth or old tee shirt while still very wet. Don’t let cleaner dry or you have to spray and start over. After done cleaning, spray with Lemon Pledge. Protects and makes cleaning next time easier. I’ve scrubbed a lot of Vermont clay, dust, grass, and cow crap off my seats and they still look almost new.
