I'm guessing you dilute the bleach by about 4 or 5 (or more?) parts
water to 1 part bleach, and let that work for say 10 minutes. Am I on
the right track?

Bleach is your friend, Power washer not. I removed a 16x32' above
ground pool a few years ago that was abutted to my deck. The wolmanized
2x12's that were exposed for the first time in 20+ years were black. I
got a brush and used straight bleach and with no effort, and I mean no
effort, the wolmanized lumber looked brand new. I used just a hose to
wash it off, no pressure washer. I have already done damage to my deck
with a pressure washer because it is very difficult not to get carried
away with stubborn spots when using a PW and weak chemicals.

If you _need_ a pressure washer to clean your deck, your cleaning
chemicals are not working and need to be stronger. I learned this the
hard way. The problem with bleach is it is not friendly to vegetation,
so if that's an issue, cover with plastic or something.I still use a
pressure washer because I can, but am very careful with it.
