mildew on Timbertech composite decking

An excellent point, even though the company recommendations include the use of • Phosphoric Acid • Oxalic Acid • Hydrochloric Acid or • Sodium Hypochlorite always use caution with any chemical.

Personally I would try to find anything that would be environmentally friendly first. Even then you have to read the fine print...

For example I found moldex deck ( http://www.envirocarecorp.com/index.php?option=com_content&task=view&id=34&Itemid=56 ) by Envirocare but further reading found it also recommends the use of bleach.

The same with fiberon ( http://fiberondecking.com/html/files/G072005_mold_mildew.pdf ) decking...
PSC also requires bleach ( http://www.psc-solutions.com/DC_Main.asp )

I would start a search of the http://www.epa.gov/ see what recommendations they have and go from there.
