Pressure wash then scrape, or vice versa?

I'm new to the forum. Thanks to everyone who reads and responds to my posts.
I have a 918 sq. ft. house that I'm prepping for exterior painting. The siding is T1-11 (a type of plywood with vertical grooves). Much of the south facing wall and parts of other walls have flaking paint that I need to remove. It makes more sense to me to scrape the paint first, then pressure wash. If I pressure wash first, then I'll have to wash the walls again to remove the debris from the scraping. Or do people think that the pressure washing will remove all the loose paint? Maybe pressure wash in conjunction with a stiff broom or brush?
Also, I want to use some kind of soap/detergent/bleach mix. I was thinking phosphate-free TSP (it exists), but I'm open to other suggestions.
Thanks for your time.
