Scrub brush and bleach if it's stained, I guess, is the other option. But I used a power washer on mine and it worked great. Any reason you don't want to do that?
I hired someone who used a gas power washer and he took some of the paint off the van body. Would an electric power washer do the job? I am willing to purchase one if powerful enough. If so any recommendations?
I used a credit card to scrape moss off mine. Took about 4 hours to do it, but came out pretty good. Pressure washing works better if you have a balcony from which you can wash it.

I also have a high end professional power washer with like a bazillion psi (with the right tip it can almost cut through concrete) and I wouldn’t get close to a vehicle with that.
Not exactly what you are asking, but just to pass along for what it's worth I recently have found that ProtectAll works exceptionally well on the PH top windows. Mine had gotten pretty "foggy" over the years and I just used this stuff on them after reading about it somewhere else and it worked fantastic. It also makes the powder coated Aluminess bumpers look great again.
