Whitewashing the deck

Submitted to Product Chat

I would like to whitewash the deck but I have a tight budget. How can I stain my deck? It has stain from 2 years ago. I cleaned the deck then applied the stain twice (2 years ago)! I have a beautiful deck that I really want to maintain as I designed it. I love whitewash and its chic look! Any advise on products to use?
