I wouldn’t recommend using a pressure washer on a deck, particularly a softwood deck. It’s easy to shred the wood fibres if you overdo it, and it’s surprisingly easy to overdo it. Soapy water, bleach and elbow grease!
Yeah, I'm aware that it's easy to over do it with a pressure washer, especially with bearings, pointing etc. But the decking has grooves in the planks where all the dirt is stuck in. Not sure I will get into it with just hand scrubbing.
