Homemade PBW - quick mix

[bduane]

The newer 3lb rectangular tub of oxiclean free has quite a bit of headspace. 1.5 lbs of red devil tsp/90 fit with room to spare in the new tub, so if you want a 2:1 mixture top off you oxiclean tub to about 3/4-1 in of headspace (see picture below).

I measured the 2:1 ratio by volume not by weight, but I assume that they are very similar in weight.

Also FYI, this cost me about $2.60 per pound, compared to the $8 per lb it costs at my LHBS for PBW.

What is red devil? Is this the exact same compound as pbw?

I believe that TSP is Tri-Sodium-Phosphate, one of the chemicals in PBW. I could be wrong, so feel free to correct.

Tell me more - is this all that's necessary to fully recreate PWB?

Red Devil TSP is Sodium Metasilicate. It's one of the ingredients, along w/sodium percarbonate and sodium carbonate, in PBW

Yes, it's not truly TSP, but "TSP substitute". Phosphates are bad for the environment (causing algae bloom in ponds from runoff, at the least) and the substitute is phosphate-free.

Why? PBW is hard to rinse(requires hot or hotter water than soaked in) and is overkill for most home brewing applications. I do use it for my cfc, but everything else is just fine with oxi, I use the cheap sun oxygen from wal mart.

From what I've read oxiclean alone isn't very effective with hard water, the tsp90 helps with that. I don't have too much trouble rinsing it off.

Thanks for the clarification!
