Wooden Deck Maintenance-Paint or Stain

I broom clean mine,they say power washing can damage the wood,plus I don't own one. After dried, it's stained with a tinted clear type stain. The deck faces south so it get beat. Should do it every year but I think I get to it every third year. Can supply name of stain if interested. BTW,when I built the deck, I stained all the wood,all sides,before assembly.
