Most of the rust particles have lost their molecular structure so they will not go to a magnet! I flushed mine because of 40 years of rust, and used electrolysis and a 200 amp battery charger. No more fumes or that nasty smell of old gasoline. Baking soda wash is cheap! Used the compressor to clear the water out of tank because it kept getting blocked, just make sure your cap isn't on because you'll blow out the fuel gauge seal....when all done....used a vacuum with a half inch water tubing to suck out all the rust.....it my case was at least a half pound of rust. Three or four years now and never a problem...I also keep it coated using marvel mystery oil in every tank full. It's alittle work, but not like taking the tank out.
