Mark, what do you mean by scale? Do you mean that varnish like glaze that coats the inside of carbs? If so, you might want to soak it in some chemical to break that down before tanking it.
I don't know if it will or not remove a good coat of varnish. It does not remove good paint, as it protects the surface from the electron flow and chemical reaction. It seems to remove about everything else though. Since the electrolyte is soap, it does a good job on grease. But like I mentioned, once you wash the residue off with soap and water the metal is really clean and unprotected so flash rusting will happen quickly. Sometimes right before your eyes kind of quickly. Get it dry and protected from humidity ASAP.
Apparently people use it often on motorcycle tanks:

If you search around you will find endless sites and examples of using electrolysis to remove rust, and as much info as you can stand from common descriptions of how/why it works to the actual chemistry of what's going on.
One thing: Do it in a ventilated area as hydrogen gas can be a byproduct, which of course explodes like the proverbial Hindenburg! It's not a huge issue; I just won't do it in the basement and then be lighting fires right around the tank. Next time I do it I'll have throw some matches at it and see what happens!
Probably not much.
If you are cleaning the inside of a tank, it does leave surface residue that must be cleaned off. A little research should answer any questions you have. It's all over the 'Net.
Glad you enjoyed the post!
Post your before and after pics! It's usually quite impressive.
