Switching from painted to stained deck

Looking to switch from a latex painted to oil stained deck. I live in Western, Massachusetts and we get all four seasons here. The deck is pretty old and weathered, no rot or algae growth. I was planning on power sanding the entire thing, and know that I will not be able to get all the paint out of the deck board imperfections (cracks, knots, dents, etc.) Was thinking of using SW SuperDeck, but after reading your articles I will probably change product. After sanding, do I need to pressure wash it? Would I need to then clean and brighten the deck? What would your recommended process be?
