What is in PBW?

[superslomo]

Can't figure out what the heck it's made out of, though it seems basically like a miracle-worker: a sink coated with paint in a bathroom under renovation in our place has been salvaged, a piece of All-Clad Stainless lost stains that have been there for years...

Yet, it says it's environmentally friendly and non-toxic? What is IN this stuff? Apart from the comment that's it's a buffered, alkaline chemical, I've found no info.

It's basically oxyclean that supposedly rinses easier. The main ingredient is sodium percarbonate. I haven't been able to tell a difference between the two.

I make my own PBW with a 60/40 mix of Oxyclean and TSP90. Same basic ingredients.

This is what I've been doing too basically. The TSP90 is sodium metasillicate. I actually bought some bulk percabonate that I'm combining with it now. It works fine but it doesn't dissolve quite as easily as the real stuff. I believe they have some other stuff in there that helps. Chelating agents, ect. Still cleans great though.

Update: Leaves 'scale' deposits on equipment for me. I believe my water is too hard for this combo without the phosphates ect. that are in PBW.
