Rust dip success stories?

I have been messing with milkstone remover to remove rust. You mix it with water in a plastic barrel. Works nicely to remove rust. First soak the part in another barrel that has a mix of lye with water to remove paint. Picture is a rusty fan shroud soaked in milkstone remover. I had to mail order the milkstone remover. About $19 a gallon thru Tractor supply. I added 10 gallons of water to the 1 gallon of MSR. I ordered two gallons for the same shipping cost.
