The molasses didn't eat up anything I put in it but I will tell you this - it stinks to high heaven. Keep it covered TIGHTLY and use a fish tank heater to keep the stuff warm.
Sorry I can't help with the ratio as i used the liquid stuff.
Did I mention it stinks ?

Buy a plastic or metal horse trough, also buy or fashion the tightest fitting lid you can because as mentioned, it reeks! Buy a 50lb sack of dry molasses powder (horse feed supply stores sell it, it's cheap) dump about half of it in the trough and fill the rest up with water (stop 8-10 inches from the top so adding parts doesn't over flow it). While at the feed store buy a water trough heater (keeps water from freezing so cattle can drink in winter) nothing fancy, most are cheap. hook up the heater, add the lid, and let it ferment for a couple weeks to a month (the warmer the faster). Once it's cooked up you can reuse it for a very long time. I've soaked 6 engine blocks in mine and the mixture has not degraded at all, a week or two and the nastiest rusty blocks are perfectly clean cast iron. I steam clean the grease off before soaking, not really required but grease can slow or stop the process where it's coating the metal.
FWIW Safest Rust Remover or Evaporust will do the same job but will cost a lot more.

Robert, I think I am way past the WD40 or solvent. To bad this engine was left sitting the way it was. Thanks Dan. Wasn't that the engine found in that civil war sub?
