Products For Cleaning Cedar Siding?

Posted this in the Pressure washing section, but thought I'd ask fellow painters as well....

I'm about to re-stain (semi-transparent) a huge rough cut cedar siding house. It hasn't had any attention in at least 10 years, so needless to say there are tons of areas of discoloration, mold, mildew, etc, etc, etc. The customers obviously want it to look like new again, however I'm a little unsure what product to use to get everything clean again.

I never really use high pressure on my power washer, but I'm especially concerned with this home because it's cedar siding and more delicate. I'm worried about lap marks and inconsistent coloration considering we're applying semi-transparent stain after cleaning and I don't want those imperfections coming through.

I normally use TSP, bleach, and water mixture, but I tested a spot and it doesn't seem to do the job without using higher pressure.

Should I use oxygenated bleach? A cleaner/brightener? Any other product suggestions? Any help would be greatly appreciated. I do have pictures of what I'm talking about if anyone wants to correspond through email: dylan@hawkinspainting.com

I'd use the oxygenated bleach plus a brightener. Restore-a-deck makes a kit that does both.
