Pressure wash is easier
Low pressure washer. Don't put it on high pressure as it will ruin your deck.
Pressure washers are inexpensive so buy one and you will find many uses for them. Around $75. You attached it to a garden hose and turn on. Can't be easier to use.
If you pressure wash (and I would) make sure to use a fan type tip or you risk damaging the wood surface.
Pressure wash. And it's so rewarding to watch!!
Thanks! Will do 😊
