We waited two years to wash and stain this new deck.  Built in 2013, I was asked to look at it and submit a bid in July 2014.  The suggestion was to wait until Spring 2015 to wash and stain.  This home is close to UCSC with southern exposure to sun.  In the second picture, the staining process has begun with the rails.  Redwood Tone Transparent..
