Re: [HSS] Rust removal with electrolysis

Unknown

 

Have any of you folks tried this?  I have
been using it on body parts of my 23 with what I consider amazing
results.  Inexpensive and safe.  I wish I had discovered it years
ago.  You need the following:  a plastic container, some scrap
steel, washing soda (eg Arm and Hammer) and a battery charger.  You
arrange the scrap steel around the sides and bottom of the plastic container
and make sure that they are all electrically bonded to each other.  This
is your anode and gets hooked to the positive terminal of the battery
charger.  Connections should be rust free at the points of connection.
 Fill the container with water and add 1 tablespoon of washing soda
(baking soda will also work) per gallon of water.  Suspend the part to be
cleaned (the cathode) so that it cannot touch the surrounding scrap. 
Hook the negative to the part to be cleaned and turn on the power.  You
will soon see small bubbles form on your part and the scrap. this will
eventually turn into a rusty foam blanket.  After a few hours, say 12 to
24, turn off the charger and lift out your part.  Use either a small
pressure washer of a Scotchbrite pad and the rust and old paint pretty much
just falls off, leaving clean metal.  Action is "line of sight" so you
may have to do some careful positioning of the anode bits so that they are
located inside a cavity or bend you are trying to clean

 

The beauty of this is that it is non toxic,
consumes very little energy and will only attack the rust, not the parent
metal.  Do not use on aluminum and other alloys.  Make sure that you
have the polarity right, positive on your scrap, negative on your part,
otherwise your part could be eaten away. I am using a 6 amp, 12 volt
charger. I can send more info and some pictures if anyone is
interested.  Maybe this is all old hat for you but I am excited by the
results.
