Preparation necessary to re-stain cedar deck

our condo handyman says that my cedar deck needs pressure washing before the yearly re-stain he recommends. my wife says that's a practice that will damage the already existing stain. she's inclined just to brush on a new layer of oil based stain. I have to say the surface now looks pretty clean and dry, and the yearly staining is preventive, and is due to the harsh sunny extremes of Arizona. any advice??

IMO it's always a good idea to wash the deck prior to recoating .... but I can't see/inspect your deck from here

If pressure washing damages the existing stain either the stain isn't in great shape or too much pressure is being used. It's also possible to chew up the wood with too much pressure You don't have to use a PWer to clean the deck. I normally mix up the cleaner [often just bleach/water] in a pump up garden sprayer, wet the deck with water then spray on the cleaner, let it set but not dry, then rinse well. A garden hose can be substituted for the PWer. Give the deck a day or three to dry before applying the stain.

Let your wife take over maintenance of the deck.

And while you're at it, let her start doing the cooking and laundry, too.

It definitely needs to be cleaned prior to applying the new coat of stain. The method that marksr is a great way to do it without potentially damaging anything.

A bleach/water solution works great here in the southeast where mildew can be an issue. Adding TSP to the mix helps if there is a lot of grime or the existing paint has a sheen. TSP can be used alone if mildew/mold is not an issue. There are also commercially prepared deck cleaners that are more user friendly but bleach is cheaper and very effective
