power-wash and clean with tsp/bleach. Or strip with maxistrip and power-wash off. I like the big woosters that attach to roller poles and I garden spray the semi-trans on and back brush with pole and brush. Saves the back!
I wait at least 2 good dry days and or use a moisture meter.
I use cabots timber oil, decking stain, and clear solutions. No matter what you use here in N. MI all you get is 1-2 years. I always recommend maintenance coats every year with a light cleaning. I can do a deck 20x20 in a 2-3 hrs cleaning included using this method. Keeps decks nice, keeps cost low, and keeps consistent business.:thumbsup:
