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?

Assuming it's a PT pine deck it's best to wash it first. It doesn't have to be pressure washed. The main thing is to get any dirt/grime removed along with any mill glazing. This also assumes the wood has had time to dry from the PT process.

It should be fine to stain a PT deck built in Sept. It generally takes 6 weeks to 6 months for the lumber to dry out from the PT process - depending on how wet it was when installed and the environment it's exposed to.

Pressure washing a wood deck if done wrong can damage the board, since the deck is new a good cleaning is probable all that is needed.

Personally I use Olympic deck cleaner (Lowes) on my composite deck, have tried others but this has always given me the best results.

A good stain is Sikkens, a bit pricey but lasts a long time!.
