Power washing a pressure treated deck built June last year

To me, it doesnt look bad, but I am going to stain it and was wondering what the advice is on weather to power wash it or not? (have never power washed before)

If so, and I use cleaner, shoudl I spray it on, then rinse with the power wash it, or put it in the the soap dispenser/tank of the washer?


If I do use the wash on the pressure washer to premix it, should I go through the deck after and rinse it off?

thanks.

I never use the siphon function on a PWer. IMO it dilutes the cleaner too much and is hard on the pump.

I'd mix up a bleach/water solution and spray it on with a pump up garden sprayer, let it set but not dry and then rinse with a PWer. A water hose will also work. It's always a good idea to clean a deck prior to applying stain - just be sure to give it enough time to dry before applying the stain.

I might add that if the deck is quite discolored and you spray quite close to better clean it you will give the surface a rough finish.
You may have to touch it up with a light sanding which is easy to do with a drywall sander on a pole.

You should never spray too close or use too much pressure to clean the deck! As noted it will chew up the wood. When the wood doesn't clean up well it is better to reapply the cleaning solution or scrub it in with an old broom. A lot less work than chewing up the wood and then having to correct it with sandpaper ....... but then I never have been overly fond of extra sanding

Good information posted ! I just thought I would add if you have storage or valuables under the deck you may want to clear the area. sometimes the bleach cleaner can be quite strong and discolor other nearby items! cheers
PS I am not a big fan of semi-clear stains for deck flooring I would stick with a solid stain they tend to last much longer!!!!
