gas tank cleaning...

my EXPERIENCE WITH MURIATIC ACID IS IT CAN BE TOO AGGRESIVE, especially the tank is thin to begin with. that acid will need to be neutralized or it can still eat away .
I had found a thread on slantsix.org. on cleaning out the engineblock and radiator with the stuff. rather involved but worked for me. seems like it was neutaalized with water and baking soda.
I can magine using it full strength???
but then i'm not a chemist, or a good mechanic for that matter!! LOL!
