Good deck cleaning chemical?

[cwenbass]

Just getting started. I cleaned a buddies deck yesterday with some home depot stuff. Not recommended probably but was easy to get around here. That being said, my buddy's deck has a lot of mold/mildew and although the dirst washed away, couldn't get it as clean as i would like. I don't want this to happen when I am doing this for $$. My machine is a 3800 psi 4 GPM. I sprayed the cleaner on with m5 x-jet and brushed it in, waited for 15 minutes and then cleaned. Any help for a noobie would be great.
Thanks

erase everything you just taught yourself and start over

Buy some sodium percarbonate and oxalic acid and try again

apply the sodium percarb or in a pinch sodium hydroxide allow it to dwell and rinse off with low pressure and the apply oxalic to brighten and neutralize, mixtures vary depending on washers and ds injector settings

How about a product like rip it from sunbrite? Not sure where to get those chemicals mentioned.

Pete the owner of Sunbrite has been in the wood business for years, if he sells it you can bet its good stuff!
