Plastisol Discharge Mix

I am really overwhelmed with this discharge game. A friend gave me a bottle of Jacquard Discharge to play with. I tried in on a couple of different color shirts. Some worked great, others not at all. I later found out that discharge does not work the same for all dye types. Ok, so thats easy to deal with. The biggest problem was the obvious smell. I was stoked with the finish but lost all of my steam when I discovered that I would need to wash the shirt after activating the discharge. I just don't want to have to wash shirts before selling them. I do my own printing and I use 95% plastisol and 5% water based ink (depending on the effect I want for that tee). I don't do large numbers of tees at a time, just a couple dozen or so at a time. I really want to work out this discharge thing so I did some research, asked some of my ink suppliers and one of them said many printers use a 'wash house' to nuertralize the discharge paste and smell. So, I did more research here to find out about wash houses and unfortunately, I'm still a little tweaked. After doing some reading suggested by people here, I now have to consider Plastisol Discharge. I didn't know this existed but its in some article suggested from here.

So does anyone know what this is? I thought discharge was water-based only? Anyone who does this regularly, who prints their own tees and does some discharge work, know what a Plastisol Discharge mix is? And do you use a wash house for small numbers (a dozen to a few dozen at a time)?

Thanks
