We just completed cleaning some used equipment using the lye bath method. Thought I'd post photos to show how we did it. This is the first time I've tried to post photos here. Hope it works.
We set the bath up in a small water tank and used two turkey fryers to heat the water up. We used 30 gals of water and 3 lbs of lye.
To hold the frames down, we used scrap chip board and drilled holes in it. A couple of block on top and we were ready to cook!!
After twenty minutes, we pulled the frames out. For this part, we used chemical resistant gloves from the hardware store, they were $6.
From there, they were laid down and rised off with a water hose until the water ran clear or no more "soap" bubbles formed on them
