Add Nuts and bolts, shake vigorously until shiny.  Wear headphones and do it while watching tv. Least expensive, just labor intensive.

I've heard electrolysis works great.  Have yet to find a reason to try it myself.

  Wayne Maxam says to tell you there is a product in the paint dept. at Canadian Tire called 'Metal Saver'.  He says he has been using this with good success on rusted tanks.  Four litres costs $25 or so, and they have been filling tanks with the solution, so depending on the tank, more than one  might be required, though it is re-usable.  I thought it sounded like phosphoric acid, but Bulldog says it leaves a shiny surface, and phosphoric acid leaves a whitish haze, so I don't know what this might be. 
  The tank lining kits come with phosphoric acid to etch the steel and dissolve existing rust, and it is not hazardous in any serious way, which  Wayne also says of this 'Metal Saver', and contrasts with some of the more adventurous acids, like muriatic - which I have always shied away from.  The electrolytic removal process sounds good, but access in a motocycle tank through the filler can be bad...

  Addendum: Wayne left a message saying the stuff he was recommending is, in fact, called 'Metal Rescue' rather than Metal Saver.

I've used rust saver also, works good and doesnt eat through the metal if you forget it for a few days

C.L.R. makes claims of dissolving rust...I have never tried it...the electrolisis method sounds interesting, however they are using battery chargers of 6 & 12 volt.  My research says electrolisis is best done at 2-3V...like a electronic equipment charger... they mention plating the tank inners with Copper. dont do this as copper reacts with gasoline....probably why there are no copper gas tanks around.. I have a few tanks to do and will be expierimenting before spring...
