  Hello Paul: There used to be a kit that used muriatic acid and as you said chain and broken glass bottles and was rotted constantly for a number of hours then a cleanser/acid neutralizer and rinse etc and finally some kind of pint/coating to inside plus paint to outside.  Guys used small portable cement mixers to do the rotating.  Many times the rust-weaken tank bottoms either broke out OR pinholes developed and the coating wasn't completely fuel resistant.  
Then radiator shops started soaking in their cleaning tanks but EPA didn't like the fuel in the acid when recycle of acid happened and most quit.  I know of one radiator shop that told me they would still 'tank' the tank and that is/was Lakewood Radiator on about 52nd and Sheridan in Arvada.  He told me $400  for Corvair tank.  You can buy new from Clarks a tank that with some 'adjusting' of the corners to match the old one will then fit into the car for $200 plus.  
Just my thoughts and others may chime in too.  Hi Linda!!
Steve

 Any suggestions on what to use and other tips on cleaning a tank?
I have been considering iso or denatured alcohol and chain/ bolts. Maybe some type of rust remover.
One search said toilet bowl cleaner._______________________________________________
