Saw something about Pine-Sol being a "bug repellant" and people use it to clean patios/decks. I have composite deck boards and just want to make sure it won't damage them.
I used to work for a building materials distributor; we moved a lot of composite decking. From what I remember the manufacturer didn't recommend leaving a cleaner on the decking, that if a cleaner was used it should be rinsed off before it has the chance to dry. I can't speak to Pine-Sol specifically, but we would use Simple Green on any boards that needed cleaning and would wipe it down with a couple rags (one to remove the excess cleaner, and a wet rag to follow up).
Edit: Here's a url for the manufacturer's product care page that we dealt with. If you know the brand of decking you have installed there ought to be a similar page on their website if there are any differences.
