Or we can just SKIP this cleaning mumbo jumbo and maybe discover a few new Lambics?
Well... it turns out that you even make your own OxyClean.
Water 1 cup
Baking Soda 1/2 cup
Hydrogen Peroxide 1/2 cup

Sound reasonable?

FYI - OxiClean Free on Amazon has jumped to $13+ for a 3lb tub. A much cheaper alternative is GreenWorks Oxi Stain Remover. It is free of dyes and perfumes and only costs $7.50. A 1lb bag of Red Devil TSP is $6.39 so for less than $14 it will make 4.5lb of homemade PBW.
I use a 2:1 mixture of Sun Oxygen Cleaner:TSP/90. It's pretty much as close a chemical equivalent you can get to PBW.
The Seventh Generation Natural Oxy Stain Remover already has the Sodium Metasilicate in it and is cheaper.
I just made some PBW from the info in this thread and am very disappointed. I used 70% Sun Oxy Cleaner and 30% Red Devil TSP/90. The Sun Oxy cleaner is sodium carbonate (cas # 497-19-8) and sodium percarbonate (cas # 15630-89-4). Nothing else. The Red Devil TSP/90 is 100% sodium metasilicate (cas # 6834-92-0).
I have used PBW for the last few years and thought it was great. It would clean anything and would rinse away fine. This homebrew, though, is awful. It seems to clean OK, but it leaves a thick, white chalky coating on everything unless you immediately scrub with soapy water and a scrubby. I just unscrewed my temp probe after running the solution through my system (at 150 degrees) and was horrified at what I saw. The coating would not come off with an aggressive scrubbing with dish detergent and hot water. I decided to leave it on to see if I could find something that will take it off without much effort so I could clean my HERMS coil with it. Oh, my poor herms coil!
Has anyone experienced this? Is there something else I can add to the mixture to prevent this terrible coating from accumulating on everything?
By the way, Cascade dishwashing detergent may contain SODIUM HYPOCHLORITE (chlorine bleach), which can not only pit stainless steel but also leave a toxic residue that can effect your beer if not fully rinsed off.

Let us know how it works out.
Try using 160F water ...My jar of PBW says 160F for CIP thats what I always aim for.
I just checked the pdf and it says 130-180F now depending on soil load.

I also always spray or run star-san on stuff treated with PBW also....I think the star san reacts with the low PH or something like that, with the residue of PBW ....as to not leave one.
That said, that warning is on a package of 100% sodium metasilicate, not a diluted down version. I mean, if Five Star are saying "Yes, PBW is 70/30 sodium percarbonate/sodium metasilicate" then surely the homemade version using those exact ingredients should be the same?.
