It all Sodium Percarbonate . Find a chemical supplier in your area and buy #50. Shouldnt run more than 35.00. Save a little for the household laundry. Sure beats paying 3.00 #.
My wife tried some on our deck. The deck needed some cleaning anyways. She cleaned something on the table and spilled some on the deck. Where it landed looked nasty> I thought I would have trouble taking care of it. About a week or two later we had a good rain and that spot looked like new wood. If you do a whole deck with it let us know how it does.
Your two questions are completely unrelated.........please in the future post in the appropriate forum, ask one question at at time. I copied the mass mailing portion of your question over to the marketing forum, which you can view at: http://www.propowerwash.com/board/upload/showthread.php?s=&threadid=2550
I used it on lattice, when I was low on safewash. It did fine, make sure you mix it with hot water, and shake often. I liked the look it gave and was not a need to nuet/brighten. Again that was mildew on lattice. As Mike said it would be expensive to whole job. It also does well on pet spot in my garage, after bulk has been removed.
