Do I need to pressure wash my new deck build in September before sealing?

I have a new deck, built in September, it's ready to be sealed. Do I need to pressure wash it first or can I just hose it off with some cleaner, as there are a few spots that are dirty?

As with any type of coating, success will be limited to the preperation. Look at the directions on the sealer and following what you read will give better results. Remember with any coating, clean, dull, dry.

If not set carefully, a pressure washer can raise a lot of grain on untreated wood deck. Probably better to to use a garden hose and a brush. Let it dry thoroughly again.
