I have forgotten, but I believe sodium hydroxide, also known as lye, takes off everything. Grease, paint, rust all the way to bare metal. Washing powder
(Arm & Hammer) takes off rust and paint, but not grease. If your tank leaks lye, you have an industrial sized mess. If it leaks washing powder, you have fertilizer.
I run a 50 gallon plastic barrel with lye in it. My first barrel had a metal drain valve at the bottom of it. It leaked. Clean up took a while. My second tank 275 gallon, is sitting and waiting for me to put it into use and quite possibly with washing powder. No metal drain valve at the bottom.
