Back in the 1960's I had access to a Tricoethylene Tank at the garage where I worked part time - I used to put engine blocks in it and leave it over the weekend. On a Monday it looked like a brand new part fresh out of the foundry - all bare metal. I believe health & safety have pretty much banned them due to carcinogenic issues. On Nurse Julies 400 project posts she mentions an acid stripper I'm sure she will tell you the what & where if you PM her.
I use Safety Clean parts cleaning fluid in mine (a mate got me a couple of gallons years ago).
