Pressure treated decks

For all of the deck experts: What is the best chemicals for the removal of algae build-up, dirt and graying on pressure treated and or composite decks? I understand using high pressure is NOT the way to go. I would like to get more aggressive in the cleaning of decks and would like to have the best possible solutions for different circumstances . Is anyone using EFC-38 wood deck cleaner, gemini's restore a deck cleaner and brightener,[FONT=&quot]pre-carbs, tsp or is using bleach the answer? [/FONT][h=1][/h]

for pressure treated decks with no old stain: apply sodium percarbonate, rinse, apply brightener (not for neutralizing but for making the color more uniform), rinse again. For composite decks: strong sh mix with plenty of dwell time, rinse, apply brightener, rinse again.

I've always used DeckBrite in the past. It works really well on wood decks and siding, But it's fairly expensive and is a pain in the ass to mix.
I've never used a separate "brightener" after SH.
Any tips on what brightener gives the best results?
