Ok, i've see so much people here advising the use of PBW - Powdered Brewery Washer. I've seen some videos, and it seems to be a very good thing for cleaning everything in homebrew stuff.

But I live in Brasil, and it can be difficult or expensive to export some of this magic powder. The same situation is there for StarSan sanitizer. Here I use a solution of peracetic acid (peroxyacetic acid), but since i've lost my dealer i'm having troubles to find it in the market.

Can anyone tell me precisely if the chemical compounds are known and how to make a Do It Yourself solution for both products buying the chemicals separately? The Homemade PBW in this recipe is safe? Thanks in advice.
