Why is Snoop so Expensive?
(OP)
Snoop leak detection fluid costs $125.00 a gallon at working strength, Seamtest concentrate costs $0.15 a gallon when diluted to working strength. Does anyone know why? Snoop claims adherance to some specifications, Seamtest does not. Any advice about other fluids or home grown formulas?

Can be tough to find soap solutions without those, and various materials are sensitive to the residues. A hint - the major component of most shampoos is sodium lauryl suflate (you could almost literally drink the stuff, it's that mild). A bigger hint, most shampoos and cleaning products then add salt and other possibly corrosive stuff, to bulk up the liquid.
Go find a pharmacy or chemical supply house and ask for some USP grade sodium lauryl sulfate.

We found that this product wets and will bubble where nothing else will.

An investigation found that the leak detection fluid used to check these cylinder valves each time they were filled or placed into service at a customer location, was actually causing stress corrosion cracking (SCC) of the brass. So in cooperation with ASTM, we came up with a standard, ASTM G186, that tested the leak detection fluid for the potential of SCC.
At the time, Snoop was found to be problematic and had significant ammonia/ammonium compounds (~ 120 ppm) which were the cause of SCC. When this was brought to the attention of Nupro (the manufacturer at the time) they reformulated their product to eliminate these trace amounts of compounds. Snoop now passes the testing for SCC per ASTM G186.
SCC is problematic for brass and copper. Not sure about other metals, but I don't think steel or SS would be subject to SCC from these compounds. Regardless, it's advisable not to use liquid detergents or other grocery store bargins. If a leak detection fluid hasn't been tested to ASTM G186, it shouldn't be allowed in service.
As a side story, we had a similar occurance years later on a copper pipe at one of our sites. We found SCC occuring in an area of copper pipe, but only in this one area. Turns out, the delivery driver was urinating on the pipe in this location because there was no bathroom in the area. So urine can also cause SCC in copper and brass alloys and shouldn't be used to detect leaks.
