Using a battery charger the positive lead hooks to metal rod, the negative lead hooks to basket? The basket is under water. Sorry but I a little confused.
If you can get a large plastic bucket, put water in it to cover the basket, add a package of baking soda, then take a car battery charger that is a few amps . take a metal rod and stand it in the water connect to the positive side of the battery,
The battery charger?
the other end contacty the basket.
The other end of the rod?
in a few mins you should see bubbles , it will remove the oxidization from the basket and overnight the rust is gone, you will then have to paint it with food grade paint but it will remove all the rust, the inside of the extractor, well like above add bleach and water, I also used dish soap, took a steel wool and cleaned the crap out of mine, one thing at the bottom there is a bearing, you have to pour boiling water into that slowly to remove the grease and nastys in there, then repack with nice grease from your bee supply house or if your like me I jammed it full of crisco. and it worked great. anything with rust can be deoxinized in the above manner. I gotta telL you onE more thing ,,DONT PUT YOUR HANDS IN THE WATER WHILE ITS PLUGGED IN . SHOCK !!!!!
