would someone who is ambitious (because I am far from it) list the price per lb of PBW and this oxy-clean free + TSP solution?

Thanks

FWIW I have made my own and it didn't work nearly as well as the real stuff.

PBW has more than 2 things in it. I usually buy it in bulk during grain buy time.

Yep... other surfactants and rinse aids. There is a podcast with the guy from Five Star floating around somewhere.

Have you made your own and compared the results? I have.

You can do, or think whatever you'd like. I have nothing to prove to you, I'm just sharing my experience.

Happy New Beer.

About $2 to $2.50 a pound using red devil tsp/90 and oxy clean free.

About $5 to $7 a pound for PBW.

From the MSDS sheet

Quote:
PRODUCT NAME: PBW
COMPOSITION: SILICATES, PHOSPHATES, AND SURFACTANTS
-----------------------------------------------------------------------------------------------------------
This product may require submission of an annual report on the release of toxic chemicals that appear in 40 CFR 372 (for SARA 313). Components present in this product at a level which reporting under the statue are:
HAZARDOUS INGREDIENTS: % TLV LIMIT IN AIR
Sodium Metasilicate (CAS# 006834-92-0) 30% 2 mg/m3 (PEL)
2 mg/m3 (OSHA)
So the 30% is right. If you've got soft water (things rinse easily) the surfactants are probably not a big deal but you are probably still going to have to put more effort into rinsing. If you have hard water you're probably going t want to figure out the surfactant.
