As far as the silica goes I thank you folks.
At the moment I am running another test with the Shout and it's at about 36 hours now. Nothing but straight Shout in a scrap of aluminum foil and at this point the brass is way cleaner than it went into the aluminum foil. No movement no nothing, just sitting on the kitchen counter top. I'll pull the brass from the aluminum foil, rinse it and let it sit on the counter top after drying to see how it will tarnish.
I'm going for simplicity here, one detergant, no fuss no muss kinda deal and I'm about sold on the Shout being the answer.
In researching the different chems used for this process it seems that acids are not a good thing at all and can promote corrosion, not detour it as well as make the brass more brittle. As far as I know the acids are used to break down case lubes which the Shout does as well as suspending it and dirt in the water.
