I got a call a few hours ago for a PT deck cleaning that has never been stained. The guy needs to have it done tomorrow and all I have on hand is 12.5%sh. Are there any good store bought cleaners or can I use my pump up with a 50/50 SH/H2o mix and rinse with low pressure. I have done a ton of houses since starting in June but hardly any decks at all. Sorry if this is a dumb question, did some searching and couldn't really find answers.

Apply roof mix, easy on the snot, dwell, rinse at 600 psi. Start at one end of a board and go to the other end with even strokes.

Collect check. Done.

This is what I have done with the few decks I have done and it turned out well. I just wasn't sure with pressure treated lumber.

You really should pass on the job until you can get some supplies and experience. Practice on some old deck boards. Practice.. practice..practice. Box stores and paint stores sell stuff.

Agreed. You should see my fence, it looks like a rainbow of wood colors.

If the deck is not super grey and dirty normal mix for me is 2 parts 12% 3 parts water and soap.Sometimes i'll brighten it depends on how the wood looks. If the deck is not going to be stained it might help to brighten to give it some color.
 
If you are going to do this I personally think 50/50 is too strong but in any event bleach will damage ant plants or vegetation so make sure you wet everything down real good prior to applying bleach solution. I'm with Shane about using a brightener, oxalic acid.
