almost free rust removal using battery charger and washing soda?

Actually I am now using EVAPO-RUST Instead, its the same stuff, but a whole lot cheaper when buying in a 5 gallon jug, It cost me $91 shipped to my door. ($65 + $26 S&H). I bought 2 gallons of the Eastwood stuff, but found out that Evapo-Rust is the same stuff and cheaper. I have bught 7 gallons so far, the stuff is bio-degradable and sewerable, I have had my hands in it many times, no problems, and it really does work. I keep looking for stuff to clean because its so much fun to pull out a perfectly clean part. (I know, I'm easily amused) Right now I have a set of Big-block heads soaking in a 5 gallon bucket. The only thing that was a bit of a lie was length of time, It takes about a week for heavily scaled and rusted pieces. The spring perches you saw tokk 4 days to derust, the snubber took about 2 days.
