Title says it all. Whad’ya think, guys? This is supposed to be cedar clapboard.
In the famous words of our very own @Innocentbystander, RUN! Ha! In all honestly though, not something I would want to tackle. I haven’t found a wood project yet that didn’t require a small amount of pressure. Obviously a small amount, but more than a simple spray and rinse. Some others may have had different results, I’m NO wood expert!

I’d say go do a test area at the lower bit, under the deck.
There’s lots that can go wrong here I think.
Stain running down, too much SH and bleaching, constant rinsing and sh1t never ceasing to come out…are just a few.

If you use SH it will turn white [like white cedar]
You don’t want to use caustics (may turn it darker) and you don’t want to use SH (may turn it lighter)…seriously, I would just use water and your favorite soap additive and see how that goes.
Your choice of description for your topic leads me to think you have limited experience with wood. If this is true, then this is not the job to “cut your wood cleaning teeth” on.
Do some fences first. Go find houses getting new fences put in and get some sections of the old fence to practice on.
IMO - what the price would be, I highly doubt the homeowner would pay. This is not a $500 house wash.

The cedar will clean easily with very low pressure. Below are before/after pics of my rental house that I washed a couple summers ago. Cedar board siding.
I didn’t use any chemicals. I tried a soap presoak but it was ineffective. The house is single story, so it was easy enough to just use my 25 nozzle and really pay attention to keeping the right distance between the wand and the wood. Cedar is soft and it’s easy to damage.
If I remember correctly, I did the whole house in about 3 hours. Staining it afterward took way longer.
