Pressure wash or scrub stucco?

The paint on my stucco on concrete block house is chalky and peeling
and even cracking in a couple of places. Everyone here, in south
Florida, seems to pressure wash stucco before painting, but I am
wondering whether scraping then scrubbing with bleach and detergent
would be just as effective.
Here's a link, hopefully, that shows the cracking paint:

The stucco has what is referred to as a smooth finish, though I've
also heard it called a sand finish. But it's basically pretty smooth,
especially with several layers of old paint on it.
If a pressure wash is the way to go, what power of washer would be
necessary to clean it up?
If scrubbing would work, what kind of mixture would be best?
Thanks.
I have a 2700 PSI 3GPM washer and I use the 40 degree nozzle so it is
a wide fan spray that knocks down the power quite a bit but goes fast.
Be careful with too much power. It will eat that stucco right off the
wall.
My 2,000 psi machine might too. It ate concrete facing off tar treated
block.
